Change subject: vc/intel/FSP2_0/CPX-SP: update to FSP ww01 release
......................................................................
vc/intel/FSP2_0/CPX-SP: update to FSP ww01 release
With Intel CPX-SP FSP ww01 release, CidBitMap field is added to
DimmDevice struct in hob_memmap.h.
The copyright statements were updated to accomodate year 2021.
gpio_fsp.h is not needed any more as coreboot takes over GPIO
configuration.

......................................................................
mb/google/volteer: Configure Delbin USB2 ports for Type C
Two USB2 ports 4 and 9 are assigned to type C connectors on Delbin board.
This update configures these USB2 ports for Type C which will allow USB2
port reset message upstream from PCH to CPU to recover a USB3 device
that downgraded to USB2 to upgrade back to USB3.
BUG=b:176575892
TEST=Booted to kernel on Delbin board and verified usb2 port reset
message enable bits through pch xhci_mmio_base + R_XHCI_MEM_U2PRM_U2PRDE
where the offset register R_XHCI_MEM_U2PRM_U2PRDE has value 0x92f4.
Validated various USB3 devices enumeration.

soc/intel/cannonlake: Allow setting PCIe subsystem IDs after FSP SiliconInit
Prevent the FSP from writing its default SVID SDID values of 8086:7270
for internal devices as this locks most of the registers. Allows the
subsystemid values set in devicetree to be used.
A description of this SSID table override behavior, along with example
code, is provided in the TigerLake FSP Integration Guide, section
15.178 ("SI_CONFIG Struct Reference").
The xHCI and HDA devices have RW/L registers rather than RW/O registers.
They can be written to multiple times but cannot be modified after
being locked, which happens during FspSiliconInit. Because coreboot
populates subsystem IDs after SiliconInit, these devices specifically
must be written beforehand or will otherwise be locked with their
default values of 0:0.
Tested by checking lspci output on System76 galp3-c (WHL), oryp5 (CFL),
and oryp6 (CML).
