mmc_spi: generate response for send status command

A "send status" command is added with the commit "mmc: checking
status after commands with R1b response". But the status register
returned from send status command of SPI protocol is different from
that of MMC/SD protocol. We do a simple test and generate a response
in stead of full bit-by-bit translation.

mmc: add generic mmc spi driver

This patch supports mmc/sd card with spi interface. It is based on
the generic mmc framework. It works with SDHC and supports multi
blocks read/write.

The crc checksum on data packet is enabled with the def,

There is a subcomamnd "mmc_spi" to setup spi bus and cs at run time.
