Hans de Goede 36a28616d4 mmc: core: Add mmc_gpiod_set_cd_config() function 
commit 63a7cd6602 upstream.

Some mmc host drivers may need to fixup a card-detection GPIO's config
to e.g. enable the GPIO controllers builtin pull-up resistor on devices
where the firmware description of the GPIO is broken (e.g. GpioInt with
PullNone instead of PullUp in ACPI DSDT).

Since this is the exception rather then the rule adding a config
parameter to mmc_gpiod_request_cd() seems undesirable, so instead
add a new mmc_gpiod_set_cd_config() function. This is simply a wrapper
to call gpiod_set_config() on the card-detect GPIO acquired through
mmc_gpiod_request_cd().
