There are platforms equipped with AMD SoC where I2C3 controller
connected to TPM device is shared between X86 and PSP. In order to
handle this, PSP acts as an I2C-arbitrator, where x86 (kernel) sends
acquire and release requests to be accepted by PSP. An example of
implementation within Linux kernel is available [1].
There is a need to introduce new ACPI_ID ("AMDI0019") so that dedicated
driver on OS side can bind to it and handle this special setup. Since
PSP takes care of I2C controller power management, we need to remove
PowerResource object from DSDT.

The and-mask passed to the gpio_update32 call needs all 32 bits to be
set to ones. When building as 32 bit binary the -1UL will result in the
needed bit mask, but for a 64 bit build the constant would have 64 bits
set to ones which then gets truncated to 32 bits causing a compiler
error. Use 0xffffffff as bit mask instead which behaves correctly in
both cases and also clarifies what this is doing.

Since the APIC bus isn't used since a long time and the IOAPIC and LAPIC
talk to each other via the system bus, there is no longer the
requirement that the IOAPIC IDs mustn't overlap with the LAPIC IDs that
start at 0 and end at CONFIG_MAX_CPUS - 1. The current Intel code uses 2
as the IOAPIC ID while most of their CPUs have more than 2 logical cores
resulting in the IOAPIC having the same ID as one of the LAPICs.
All chipsets in soc/amd use the defines for FCH_IOAPIC_ID and
GNB_IOAPIC_ID for initializing the IOAPIC register, writing both MADT
and IVRS ACPI tables and there's no MPTable support for those SoCs that
might also rely on those IDs being consistent.
This patch changes the definitions for FCH_IOAPIC_ID and GNB_IOAPIC_ID
from CONFIG_MAX_CPUS and CONFIG_MAX_CPUS + 1 to 0 and 1. This also makes
sure that the IOAPIC IDs still fit in 4 bits despite Cezanne having a
CONFIG_MAX_CPUS of 16 resulting in the IOAPIC IDs being larger than 4
bits with the old code. While the Cezanne FCH IOAPIC supports 8 bits of
IOAPIC IDs, this is non-standard.

Currently apu/amdfw_a-position and apu/amdfw_b-position currently depend on CEZANNE_FW_A_POSITION and CEZANNE_FW_B_POSITION. This causes error messages from awk as these variables are sourced from fmap_config.h and these variables are expanded before fmap_config.h is built. However these variables should not be set to CEZANNE_FW_*_POSITION. These files end up in the FW_MAIN_* fmap regions. These regions are placed at the proper locations through the chromeos.fmd file. The apu/amdfw_*-position variables are the positions within these regions where the files end up. These variables should be set to 0x40 to coincide with the beginning of the FW_MAIN_* regions, accounting for the size of struct cbfs_file + filename + metadata, aligned to 64 bytes. Currently they end up in the correct locations only because fmap_config.h does not exist when the apu/amdfw_*-position variables are expanded.
This change explicity sets the value of these variables to 0x40, removing the errors from awk and ensuring that these files end up in the correct location in the resulting image. These changes are also applied to the Picasso and Sabrina makefiles as well.
