When fw_config is unprovisioned, devicetree will disable all probed
devices. However, boot-critical devices such as storage devices need to
be enabled.
As a temporary workaround while adding devicetree support for this,
remove the fw_config probe for storage devices so that all storage
devices are always enabled. On eMMC SKUs, UFS and ISH will be disabled
by the PCI scan anyway. On UFS SKUs, eMMC is not disabled by the PCI
scan, but keeping it enabled should have no functional impact, only a
possible power impact.

Rename get_smee_reserved_address_bits to get_sme_reserved_address_bits
since the feature is called secure memory encryption and the last 'e' in
SMEE bit in the SYSCFG MSR just stands for enable. The function will
return a valid number of reserved address bits no matter if this is
enabled or not, so drop the second 'e'.

Since cmos.default is applied early in bootblock, the EC BRAM interface

Instead of adding the new PCI IDs of the XHCI controllers in every new
chip generation to the pci_xhci driver, bind the driver to the internal
PCI devices of the XHCI controllers via the device ops statement in the
chipset devicetree. The PCI device function of the XHCI2 controller in
Mendocino can be either a dummy device or the XHCI controller, so the
device ops are attached to that device in the mainboard devicetree
instead. The Glinda code is right now just a copy of the Mendocino code,
so it'll change in the future, but for consistency the equivalent
changes to those in Mendocino are applied there too.
Since the device ops are now attached to the devices via the static
devicetree entry, also remove both the xhci_pci_driver struct and the
amd_pci_device_ids array from drivers/usb/pci_xhci/pci_xhci.c.
TEST=SSDT entries for the XHCI controllers are still generated on
Mandolin.
