dev_dbg() in any case prints the device and driver name, no need
to repeat this in (some) messages. Drop duplicates for good.

Since we don't use structure field layout randomization
the manual shuffling can affect some macros, in particular
container_of() against struct of_mmc_spi, which becomes
a no-op when pdata member is the first one in the structure.
