The response type of the SD_APP_OP_COND command is correctly
determined using the mmc_resp_type macro, because the only use of that
opcode, mmc_send_app_op_cond, correctly places MMC_RSP_R3 in cmd.flags.
So there is no need to treat that opcode separately.

Currently the base address for all io operations is hidden behind a

and all functions set base = host->base. This is hard to read, so the
whole wrapping is removed and host->base is directly inserted in the
io access.

In the current code, msdc_clr_fifo is a macro and just busy waits for
a limited amount of time for the fifo clear to finish. That is not
correct, the programming manual hits, that the user should wait until
the bit is cleared by hardware and not a limited amount of time.
So the code is changed to a function, that also relaxes the cpu while
busy waiting.

The BUG_ON() removed by this patch is just a duplicate of a prior
BUG_ON() statement. There the condition is just clearer, it checks
weather sglen > MAX_BD_NUM and MAX_BD_NUM is equal MAX_BD_PER_GPD. So
this statement can be safely removed.

Current code uses two functions for dma setup, msdc_dma_config and

msdc_dma_config, so the later one can be inline into the first
