Hash :29206d63 Message :Apparently one of the main concepts in the SDMMC I/O subsystem is that
the driver attached to an SDIO card always holds the lock and only
releases it once it detaches. Now with that in mind, some time ago
sdmmc_io_function_disable() and sdmmc_io_function_ready() were changed
to only assert the write lock and not take it, but not all of the tree
was converted. Change sdmmc_io_function_enable() as well, and remove
the enter/exit dance in the interrupt code. Apparently there is no
SDIO driver yet/anymore which would trigger those issues.
