The DMA operation in SDIO CMD53 may fail because the 4 bit SDIO mode
is not set up correctly on BF548.
Remove 2 blank lines as well.

Hi Chris,
Could you review this series of patches for Blackfin on-chip SD
controller? The head file and new BF60x machine code have been merged
upstream. These patches are necessary to get SD driver built on BF60x.
Thanks

In BF60x RSI controller:
1) MMR read/write width differs.
2) PWR and CTL MMRs are merged to together.
3) ROD and PD_DAT3 bit masks are obsolete.
4) New RSI block size MMR is defined.
5) The definition of DMA descriptor set size is changed.
6) set_ios should powers up controller
From: Sonic Zhang
Without reset, SD controller may stay in disable mode, SD card can't
be detected when resume from power saving mode.

mmc core suspend and resume functions had already called sdh_set_ios with
proper flags.
