Sansa AMS: Move the boost from SD ident to operating frequency to after the cards get switched to HS timings.
It seems that lowering the operating frequency for the SD cards has made some uSD cards have problems with the init process.
By moving the boost from ident to operating frequency to after the switch to HS timing these card now seem to init normally.
We still need to fix the problem where the internal cards and non HS uSD cards are still slightly overclocked at 31 MHz.
As of now we experience data crc failures during writes at the next lower frequency of 15.5 MHz.
