mmc_spi patch

[Hajime Ishitani]

Hello all,

This patch add latency of a re-try in BUSY being waiting
for after writing.
The timeout uses CSD register setting, and really calculated.

And "devs_disk_mmc.cdl" Just fixed a missed "}".

I tested it in TOSHIBA SD-M02G and Panasonic SDH512.
High capacity SD has the situation when BUSY is slow.

Thanks
Hajime Ishitani
