add firmware/driver/sd.c which contains common code between SD drivers

ingenic SD driver needs more cleanup so it still doesn't use the common code
correct a comment in hotswap.c: card_extract_bits assume most significant word of register first (so, use this order)
fix debug menu which used MMC specific commands / bits positions in csd/cid
move the default block size of 512 into sd.h
move the mantissa & exponent table into a single file (sd.c) to reduce binsize. we don't need to export it anymore anyway

TODO : ingenic cleanup (will happen soon so building sd.c is not conditional)
