Sansa AMS: Force sd_enable(true) when using the Debug View HW info page so we can read the registers immediately.

Browse source 
Because we turn off the clocks to the SD controllers between disk accesses we were unable to read the MCI_CLOCK registers until there was a disk access.  Now we can read them immediately.
