The variable cmd in the function msdc_tune_request is set but never
used, so remove it.

The current code uses a macro (sdr_write32) for writing to hardware,
but it is only a writel with switched arguments, so replace it to get

Here are the next cleanups for the mt7621-mmc driver. Again much of
unused code is removed and the IO is cleaned up. The next major step
will be the complete refactoring of the tuning, because it does not
use the tuning capabilities of sd-core, but kind of re-implements that.

determined using the mmc_resp_type macro, because the only use of that
opcode, mmc_send_op_cond, correctly places MMC_RSP_R3 in cmd.flags.
So there is no need to treat that opcode separately.

driver does the same, so remove the basic mode code.

The function uffs that is implemented by this driver returns the same
values as the kernel function ffs. So the uffs function is removed and
the calls to it are replaced with calls to ffs.

Current code uses linked DMA mode only when there is more than one
entry in the scatterlist. But the overhead of the linked DMA is very
small, so the code is easier when only using linked DMA and this is
also the way, the upstream driver mtk-sd handles it.
