Until now some FSP-S parameters were configured for Siemens APL
mainboards via the Binary Configuration Tool (BCT). For simplification,
the original APL FSP binary should now be used. For this purpose, the
corresponding FSP-S parameters are set via devicetree, respectively via
mainboard_silicon_init_params accordingly.
The following parameters are affected:
- Disable CPU power states (C-states)
- Set lowest Max Pkg Cstate - PkgC0C1
- Disable PCIe Hot Plug for all enabled RPs
- Disable PCIe Transmitter Half Swing for all RPs
- Disable PCIe Active State Power Management (ASPM) for all RPs
- Disable PCIe L1 Substates for all RPs
TEST:
- Compare old with new coreboot log on mc_apl5, found no differences
- Boot Linux v4.4 and check output of 'lspci'

The BACKLIGHT_ENABLE pin on this board unfortunately defaults to a
pull-up on power on, meaning the backlight is immediately enabled. Best
we can do about that is to turn it off again early and wait until it is
actually correct in the panel power sequence to turn it back on.
Some panels want an explicit 80ms delay after training the eDP
connection before the backlight is turned on (this is probably just to
avoid temporary display artifacts, but whatever). We don't want to
busy-wait that extra time, so instead just delegate turning on that GPIO
to the payload (which is also in charge of the backlight PWM already).

current case (> 3.5A) and is at 2.5Mhz with low current case(< 2.8A).
The switch frequency of vgpu should be kept at 2.5Mhz.
The root cause is that phase config of vcore is not disabled, it will
affect the switch frequency of vgpu. Corret the phase setting at
initialization.
