Move the parts of romstage.c that populate the UPD-M data structure to
the newly created fsp_m_params.c file. Since
platform_fsp_memory_init_params_cb gets called from the FSP driver and
not directly from car_stage_entry the two code parts in romstage.c
weren't directly interacting. Since soc/romstage.h only contains the
mainboard_updm_update function prototype, rename it to soc/fsp.h. This
patch also removes a few unused includes.

This file populates the UPD-S data structure that gets passed to the
FSP-S, so add that s part to make it a bit clearer which FSP parameters
it'll set up. This is also a preparation to add a fsp_m_params.c file in
the following patches.

The KBRST_L pin will cause a reset when driven or pulled low even when
the GPIO mux is set to GPIO and not native function. So when you want to
use that pin as general purpose output the keyboard reset input
functionality needs to be disabled by selecting this option in the
board's Kconfig file to avoid causing a reset by writing a 0 to the
output level bit when it's configured as an output.

Until now every AML package had to be closed using acpigen_pop_len().
This commit introduces set of package closing functions corresponding
with their opening function names. For example acpigen_write_if()
opens if-statement package, acpigen_write_if_end() closes it.
Now acpigen_write_else() closes previously opened acpigen_write_if(),
so acpigen_pop_len() is not required before it.

I2C driver is replicated in each generation of AMD SoCs. Introduce a
common I2C driver that can be used across all the AMD SoCs. To begin
with, peripheral reset functionality is moved into this common driver.
SoC specific I2C driver passes the SCL pin configuration in order for
the common driver to reset the peripherals. More functionality can be
moved here in subsequent changes.
Also sb_reset_i2c_slaves() is renamed as sb_reset_i2c_peripherals() as
an effort towards using inclusive language.

PSP_SHAREDMEM_BASE made the assumption that _psp_sharedmem_dram would
only match once. With CB:49332 there are now two symbols, and it was
grabbing the wrong one.
This change makes it so we match the exact symbol. It also switches to
using awk to simplify the code.
The bootblock.elf target that is added to the list of prerequisites also
creates the bootblock.map file that gets used to extract the base
address of the _psp_sharedmem_dram symbol.

This will also be used for cezanne. Stoney also has a similar function,
but it hard codes the scope path. I didn't have a device setup to test
if switching to this function was a no-op. So I left it.
TOM2 isn't used by any ASL, so we could remove it later.
