Previously the ME PCI interface (HECI) was being reported as present in
the DMAR ACPI table even when ME firmware was missing or the PCI device
was hidden and HECI would be unresponsive.
Now we check via the PCI config space itself to verify if the HECI
is present or not.
Note that this test could fail if ME firmware is present but
HECI is disabled in devicetree, because it would not advertise that the HECI
exists even though there is a running ME. Perhaps this behaviour is desirable
because in this case you won't see the HECI in the lspci tree anyway.

The early TPM probe was done directly in tis.c ignoring the lower
layer that provides appropriate access to the chip. Move this into
a tpm_vendor_probe() function so it can use iic_tpm_read() with all
of the built-in delays and semantics instead of calling i2c_readb()
directly from the wrong layer.
This fixes early init failures that were seen with the cr50 i2c tpm
on the reef mainboard.

For an unknown reason the printed address in the SPI debug messages is
modified before it is printed by subtracting the constant 0xf020 from
the passed in address.
What I suppose this debug code should do is to print the used register
address within the SPI controller while any parts of this address that
belongs to the SPI base address should be omitted. To fix that remove
the subtraction of 0xf020 and adjust the address mask to 0x3ff so that
only the offset to the registers inside the SPI controller will be
visible in the debug messages.
In addition switch to uint8_t and friends over u8 to sync up with used
types in this file.

According to "G45: Volume 3: Display Register

G35 Express Chipset Graphics Controller" some registries
are set incorrectly in gm45/gma.c.
Some values are changed after comparing them with the values
the i915 linux kernel (3.13 was used) module sets while modesetting.
The values were obtained using 'intel_reg' from intel-gpu-tools,
during a normal boot and with 'nomodeset' as a kernel argument.
Some registers that don't exist on gm45 are set in gma.c, which is
probably the result of copying code from a more recent intel
northbridge.
The result is that that gm45 laptops with wxga displays still work as
before. gm45 laptops with wxga+ or higher resolution now just work,
where previously a black screen was shown.
TEST: build with native graphic init and flash on a gm45 target, like

Add support for the cr50 TPM used in apollolake chromebooks.
This requires custom handling due to chip limitations, which
may be revisited but are needed to get things working today.
- timeouts need to be longer
- must use the older style write+wait+read read protocol
- all 4 bytes of status register must be read at once
- same limitation applies when reading burst count from status reg
- burst count max is 63 bytes, and burst count behaves
slightly differently than other I2C TPMs
- TPM expects the host to drain the full burst count (63 bytes)
from the FIFO on a read
Luckily the existing driver provides most abstraction needed to
make this work seamlessly. To maximize code re-use the support
for cr50 is added directly instead of as a separate driver and the
style is kept similar to the rest of the driver code.
This was tested with the cr50 TPM on a reef board with vboot
use of TPM for secdata storage and factory initialization.
