According to the PCIe CEM specification, the deassertion of PERST#
should occur at least 100ms after the assertion. To ensure the 100ms
delay requirement is met, calculate the elapsed time since assertion. If
it is smaller than 100ms, do an extra delay.

Described in PCIe CEM specification sections 2.2 (PERST# Signal) and
2.2.1 (Initial Power-Up (G3 to S0)). The deassertion of PERST# should be
delayed 100ms (TPVPERL) for the power and clock to become stable.
Instead of asserting PERST# right before PCIe initialization and waiting
for 100ms, which is currently the only function of 'mtk_pcie_pre_init',
so that the extra 100ms delay in ramstage is avoided.

This patch implements coreboot native debug handler to manage the FSP
event messages.
`FSP Event Handlers` feature introduced in FSP to generate event
messages to aid in the debugging of firmware issues. This eliminates
the need for FSP to directly write debug messages to the UART and FSP
might not need to know the board related UART port configuration.
Instead FSP signals the bootloader to inform it of a new debug message.
This allows the coreboot to provide board specific methods of reporting
debug messages, example: legacy UART or LPSS UART etc.
This implementation has several advantages as:
1. FSP relies on XIP `DebugLib` driver even while printing FSP-S debug
messages, hence, without ROM being cached, post `romstage` would
results into sluggish boot with FSP debug enabled.
This patch utilities coreboot native debug implementation which is
XIP during FSP-M and relocatable to DRAM based resource for FSP-S.
2. This patch simplifies the FSP DebugLib implementation and remove the
need to have serial port library. Instead coreboot `printk` can be
used for display FSP serial messages. Additionally, unifies the debug
library between coreboot and FSP.
3. This patch is also useful to get debug prints even with FSP
non-serial image (refer to `Note` below) as FSP PEIMs are now
leveraging coreboot debug library instead FSP `NULL` DebugLib
reference for release build.
4. Can optimize the FSP binary size by removing the DebugLib dependency
from most of FSP PEIMs, for example: on Alder Lake FSP-M debug binary
size is reduced by ~100KB+ and FSP-S debug library size is also
reduced by ~300KB+ (FSP-S debug and release binary size is exactly
same with this code changes). The total savings is ~400KB for each
FSP copy, and in case of Chrome AP firmware with 3 copies, the total
savings would be 400KB * 3 = ~1.2MB.
Note: Need to modify FSP source code to remove `MDEPKG_NDEBUG` as
compilation flag for release build and generate FSP binary with non-NULL
FSP debug wrapper module injected (to allow FSP event handler to execute
even with FSP non-serial image) in the final FSP.fd.

TEST=Able to build and boot brya. Also, verified the FSP debug log is
exactly same before and with this code change.

Vendorcode is messy so instead of trying to fix the warnings thrown by
clang ignore them on AGESA platforms.

Clang complains that the terniary '?' operator is executed before the
bitwise '|'. This is true and desired in this case. Being explicit
about won't hurt however.
