soc/amd/stoneyridge: Add ACPI D3Cold support for SD Controller
We need to support entering D3Cold from the OS to work around a bug in
the SDHC where the data lines get stuck always reading zeros.
BUG=b:122749418
TEST=Verified the linux kernel can transition between D3 and D0. Also
verified that the device can suspend and resume and continue to have a
functioning SD controller after.
