Add the `eeprom_read_serial()` function to read serials from the EEPROM.
Note that there's only one buffer now: this means only one serial can be
accessed at the same time, and the buffer needs to be cleared so that it
does not contain old data from other serials. Given that the serials are
copied one at a time into SMBIOS tables, having one shared buffer is not
a problem.

The PCH's SGPIO pads are connected to a buffer chip that is powered from
the always-on +3V3_AUX rail. For some cursed reason, when the SGPIO pads
stay configured as SGPIO when a Poseidon system shuts down, voltage from
the +3V3_AUX-powered buffer chip will leak into the +5V rail through the
SATA backplane. Just pulling the SGPIO pads low before the system powers
off stops the +5V rail from being cross-powered.
This issue has only been observed in S5, but it's very likely other
sleep states are affected as well. Thus, always pull the SGPIO pins
low before entering ACPI S3 or deeper because the power supply will
turn off in these states as well.
TEST=Obtain a Poseidon system, verify that the +5V rail is cross-powered
after going to S5. We measured 0.17V on our system, but voltages as
high as 0.6V were measured on other systems. Verify that unplugging
the SGPIO cable going to the SATA backplane results in the +5V rail
voltage dropping to 0V, which indicates that the voltage leakage is
exclusively coming from the SGPIO and SATA backplane. Finally, make
sure that the +5V rail voltage drops to 0V after going into ACPI S5
with this patch applied and the SGPIO cable connected.

RaptorLake introduces the support of the Voltage Regulator Fast Vmode
feature. When enabled, it makes the SoC throttle when the current
exceeds the I_TRIP threshold. This threshold should be between
Iccmax.app and Iccmax and take into account the specification of the
Voltage Regulator of the system.
This change provides a mean to:
1. Enable the feature via the `vr_config->enable_fast_vmode'. If no
I_TRIP value is supplied FSPs picks an adapted I_TRIP value for
the current SoC assuming a Voltage Regulator error accuracy of
6.5%.
2. Set the I_TRIP threshold via the `vr_config->fast_vmode_i_trip'
field.
These new fields are considered independent from the other `vr_config'
fields so that the board configuration does not have to unnecessarily
supply other VR settings to enable Fast VMode.
Information about the Fast VMode Feature can be found in the following
Intel documents:
- 627270 ADL and RPL Processor Family Core and Uncore BIOS
Specification
- 724220 RaptorLake Platform Fast V-Mode
- 686872 RaptorLake Lake U P H Platform
