mb/google/rex: Add PCIe based SD controller

This patch adds PCIe based SD controller at RP 7 (from RP 11) with
Proto 1 schematics dated 11/30.

Additionally, added the RTD3 entries for the SD controller.

Finally, ensured that EN_PP3300_SD (GPP_D03) is configured in
bootblock and SD_PERST_L (GPP_D02) is configured in romstage to
meet the power cycle requirement.

BUG=b:242917011
TEST=Able to build and boot Google/Rex. SD card detection is due
for the Proto 1 hardware.
