rtemsbsd/arasan_sdhci: Stop masking capabilities

Browse Source 
The initial version of this driver was masking the capabilities register
to hide 8 bit bus capability. This is not necessary since these devices
report that capability correctly and the masking affects performance
negatively on ZynqMP boards where the 8 bit bus is supported. This also
removes two quirks that were made necessary by the capabilities masking.
