This patch removes the recently added update8/16/32/64() API and
replaces it with clrsetbits8/16/32/64(). This is more in line with the
existing endian-specific clrsetbits_le16/32/64() functions that have
been used for this task on some platforms already. Rename clrsetbits_8()
to clrsetbits8() to be in line with the new naming.
Keep this stuff in <device/mmio.h> and get rid of <mmio.h> again because
having both is confusing and we seem to have been standardizing on
<device/mmio.h> as the standard arch-independent header that all
platforms should include already.
Also sync libpayload back up with what we have in coreboot. (I'm the
original author of the clrsetbits_le32-definitions so I'm relicensing
them to BSD here.)

Most of the current implementations for FSP-based platforms
make (sometimes wrong) assumptions how FSP reorders root ports
and what is specified in the devicetree. We don't have to make
assumptions though, and can read the root-port number from the
PCIe link capapilities (LCAP) instead. This is also what we do
in ASL code for years already.
This new implementation acts solely on information read from
the PCI config space. In a first round, we scan all possible
DEVFNs and store which root port has that DEVFN now. Then, we
walk through the devicetree that still only knows devices that
were originally mentioned in `devicetree.cb`, update device
paths and unlink vanished devices.
To be most compatible, we work with the following constraints:
o Use only standard PCI config registers.
o Most notable, don't try to read the registers that
configure the function numbers. FSP has undocumented
ways to block access to non-standard registers.
o Don't make assumptions what function is assigned to
hidden devices.
The following assumptions were made, though:
o The absolute root-port numbering as documented in
datasheets matches what is read from LCAP.
o This numbering doesn't contain any gaps.
o Original root-port function numbers below a PCI
device start at function zero and also don't
contain any gaps.

So, the PCI to PCI bridge specification had a pitfall for us:
Originally, when decoding i/o ports for legacy VGA cycles, bridges
should only consider the 10 least significant bits of the port address.
This means all VGA registers were aliased every 1024 ports!
e.g. 0x3b0 was also decoded as 0x7b0, 0xbb0 etc.
However, it seems, we never reserved the aliased ports, resulting in
silent conflicts we preallocated resources. We neither use much
external VGA nor many i/o ports these days, so nobody noticed.
To avoid this mess, a bridge control bit (VGA16) was introduced in
2003 to enable decoding of 16-bit port addresses. As older systems
seem rather safe and well tested, and newer systems should support
this bit, we'll use it if possible and only warn if not.
With old (AGP era) hardware one will likely encounter a warning like
this:
found VGA at PCI: 06:00.0
A bridge on the path doesn't support 16-bit VGA decoding!
This is not generally fatal, but makes unnoticed resource conflicts
more likely.

When accessing register with multiple bit fields, the common approach is
to use clrsetbits_le32, for example:
clrsetbits(®, (1 << 0) | (0x3 << 1) | (0x7 << 10),
(1 << 0) | (0x1 << 1) | (0x5 << 10));
This hard to maintain because we have to calculate the mask values
manually, make sure the duplicated shift (offset) was set correctly.
And it may be even worse if the value to set will be based on some
runtime values (that many developers will do a if-block with two very
similar argument list), and leaving lots of magic numbers.
We want to encourage developers always giving field names, and have a
better way of setting fields. The proposed utility macros are:
DEFINE_BITFIELD(name, high_bit, low_bit)
EXTRACT_BITFIELD(value, name)
WRITE32_BITFIELDS(addr, name, value, [name2, value2, ...])
READ32_BITFIELD(addr, name)
Where a developer can easily convert from data sheet like
BITS NAME
26:24 SEC_VIO
Into a declaration
DEFINE_BITFIELD(SEC_VIO, 26, 24)
Then, a simple call can set the field as:
WRITE32_BITFIELDS(®, SEC_VIO, 2);
That is much easier to understand than
clrsetbits_le32(®, 0x7 << 24, 0x2 << 24);
And to extract the value:
READ32_BITFIELD(®, SEC_VIO)
That is equivalent to:
(read32(®) & 0x3) >> 24

Many peripheral drivers across different SoCs regularly face the same
task of piping a transfer buffer into (or reading it out of) a 32-bit
FIFO register. Sometimes it's just one register, sometimes a whole array
of registers. Sometimes you actually transfer 4 bytes per register
read/write, sometimes only 2 (or even 1). Sometimes writes need to be
prefixed with one or two command bytes which makes the actual payload
buffer "misaligned" in relation to the FIFO and requires a bunch of
tricky bit packing logic to get right. Most of the times transfer
lengths are not guaranteed to be divisible by 4, which also requires a
bunch of logic to treat the potential unaligned end of the transfer
correctly.
We have a dozen different implementations of this same pattern across
coreboot. This patch introduces a new family of helper functions that
aims to solve all these use cases once and for all (*fingers crossed*).
