Our AArch64 code supports dynamic framebuffer allocation which
makes it necessary to change the framebuffer information during
runtime. Having a pointer inside `libsysinfo` made a mess of it
as the pointer would either refer to the original struct inside
the coreboot table or to a new struct inside payload space. The
latter would be unaffected by a relocation of the payload.
Instead of the pointer, we'll always keep a copy of the whole
struct, which can be altered on demand without affecting the
coreboot table. To align the `video/graphics` driver with the
console driver, we also replace `fbaddr` with a macro `FB` that
calls phys_to_virt().

Same as with other consoles and drivers that cache an address
outside the payload (e.g. video/corebootfb), we should store the
physical address, so we can derive the virtual address on demand.
This makes it save to use the address across relocations.
As a first step in migrating `libsysinfo` to `uintptr_t`, we
also switch to the physical address there.
Fixes the default build of FILO, tested with Qemu/i440FX and Qemu/Q35.

Since Puff uses CSE Lite SKU that supports in-field CSME
updates an additional reset is triggered when jmp from RO
to RW during boot. However this reset is not detected by
the cr50 running older firmware because the strapping
configuration for EFS2 uses PLT_RST_L to assert to cr50
that a AP reset occured. The older cr50 firmware
version of 0.0.22 only monitors AP resets via SYS_RESET_L
and hence never detects the reset.
To mitigate the issue above a modified reset sequence is
required to be performed to signal the reset occured and
hence a board-specific cse_board_reset() strong symbol is
provided to modify the flow accordingly.

According to the IT8728F datasheet it is possible to add an extra delay
between 3VSBSW# being set and PWRGD3 being set during resume from
Suspend-to-RAM. This is enabled in the special function selection
register, the default being 0.
This is also useful for the IT8720F although this chip does not have the
PWRGD3 output. On the corresponding pin it has PWROK2, which the setting
then seems to apply to.
The datasheet for the IT8720F marks the corresponding bit as reserved,
but the vendor BIOS of an Acer Aspire M3800 sets it anyway. Without
setting the bit, coreboot fails to resume from S3. Oscilloscope
measurements have shown that setting the bit increases the delay between
3VSBSW# being set and PWROK2 being set from around 1 us to 140 ms. The
actual use of PWROK2 on the board design is unclear - the only
destination it seems to reach is a pin header near the SuperIO marked as
"GPIO1".

AMD indicates they did this because they were concerned with certain
panels flickering at lower backlight values. However, for unaffected
panels it's desirable to be able to have the panel "turn off" at
the lowest backlight setting. The only way to do that is to provide
ATIF bindings that indicate backlight range.
Option SOC_AMD_COMMON_BLOCK_GRAPHICS_ATIF is added to provide a full
range for the backlight setting. If needed, this path can be built upon
for fuller support, but for the time being this is the only thing
necessary to make the backlight be full range.

Compiler's instrumentation cannot insert asan memory checks in
case of memory functions like memset, memcpy and memmove as they
are written in assembly.
So, we need to manually check the memory state before performing
each of these operations to ensure that ASan is triggered in case
of bad access.
