mb/siemens/{mc_apl1,...,mc_apl6}: Configure FSP-S UPDs
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'
