soc/amd/stoneyridge: Remove unused SD controller

Remove the unused support code from the old multi-device hudson
SD controller.  The binaryPI blob contains the correct steps
for setting up SD and the public BKDG doesn't completely document
the controller.

The sd.c file was using device IDs not associated with the Stoney
Ridge APU.  The hudson_enable() code removed was also looking for
incorrect device IDs and the PM_MANUAL_RESET register doesn't
behave as the source indicates.

The SD default settings may be overridden.  Future improvements
may include a few Kconfig options and a weak call to the mainboard
for overriding additional defaults.
