Patch all drivers which use mmc_regulator_set_vqmmc() and prepare them for
the fact that mmc_regulator_set_vqmmc() can return a value > 0, which would
happen if the signal voltage switch did NOT happen, because the voltage was
already set correctly.

The hs_timing_cfg[] array is indexed using a value derived from the
"mshcN" alias in DT, which may lead to an out-of-bounds access.
Fix this by adding a range check.

The array hs_timing_cfg is local to the source and does not need to
be in global scope, so make it static.
Cleans up sparse warning:
symbol 'hs_timing_cfg' was not declared. Should it be static?

There are currently no external users of the public dw_mmc header file,
except the dw_mmc driver itself. Therefore let's move the definitions from
the public dw_mmc header file into the existing private dw_mmc header file
and then remove the public one.

Let's migrate it to use runtime PM and remove the system
PM callback from this driver. With this patch, it could
handle system PM properly and could also use runtime PM
if we enable it.
