There has been problems that for some paths that clock are not stopped
during new command programming and initiation. Result is issuing
of incorrect command to the card. Some other problems are cleaned too.
Noisy report of known ERRATUM #4 has been suppressed.

Rather than having every driver duplicate the set_ios debugging,
provide a single version in mmc.c which can be expanded as we
add additional functionality.

Rather than each driver test MMC_DEBUG itself, and define DEBUG,
pass it in via the makefile instead.
Fix drivers to use pr_debug() where appropriate, and avoid defining
a DEBUG() macro.

MODULE_PARM was actually breaking: recent gcc version optimize them out as
unused. It's time to replace the last users, which are generally in the
most unloved drivers anyway.

drivers/mmc/au1xmmc.c doesn't compile because commit
e92251762d02a46177d4105d1744041e3f8bc465 introduced a typo and passes
the wrong argument to the mmc_resp_type macro.
Error because of the typo:

drivers/mmc/au1xmmc.c currently doesn't compile; it needs to be
converted to use platform_driver. I cannot test this change because
of lack of hardware but I followed the drivers this one is based on,
and the code is certainly not worse than before.
drivers/mmc/au1xmmc.c: At top level:
drivers/mmc/au1xmmc.c:1002: error: ‘platform_bus_type’ undeclared here (not in a function)
make[2]: *** [drivers/mmc/au1xmmc.o] Error 1

Some hosts need to know the command type, so pass it via a set of
flags in cmd->flags.
