Pushing EOP msg post FSP notify helps to save ~30ms+ boot time across
various warm reboots.
This patch ensures late sending EOP msg when function disabling of CSE
is no longer a requirement.

Prior to coreboot sending EOP messages during post, it's important to
ensure that CSE is not in Idle state. In case CSE is in Dev Idle
state (which means D0I3 bit is set), reset this bit before sending
EOP command.
This patch ensures coreboot has provision to send CSE EOP messages even
after the FSP Notify phase without any delays waiting for the device
to respond or timeout.

In CB:52662 when MIPI display support was added, we accidentally changed
the code flow for eDP displays such that i2c_init() will no longer be
called when display_init_required() is false. This is a problem because
on this platform, i2c_init() does not just prepare the I2C controller
for firmware use, it also loads firmware to the controller that makes it
behave like an I2C device in the first place -- a step that the kernel
cannot later do on its own if the firmware didn't already do it.
Skipping this initialization means the I2C controller becomes unusable
to the kernel.
This patch fixes the issue by making the i2c_init() unconditional again.

The %fs and %gs segment are typically used to implement thread local
storage or cpu local storage. We don't currently use these in coreboot,
so there is no reason to map them. By setting the segment index to 0,
it disables the segment. If an instruction tries to read from one of
these segments an exception will be raised.
The end goal is to make cpu_info() use the %gs segment. This will remove
the stack alignment requirements and fix smm_do_relocation.

The voltage rail discharge times have been measured, so therefore
the boot time on a cold boot when the CSE must go through a global reset
and thus a trip to S5 can be optimized. Select the lowest applicable
value for each PchPmSlp UPD that can be used with these measurements.
This is programmed in the baseboard because the measured discharge times
leave (what should be) plenty of margin for variants to also not violate
any power sequencing guidelines from the PDG.
