mmc: core: Rework wp-gpio handling
[ Upstream commit 9073d10b098973519044f5fcdc25586810b435da ]
Use MMC_CAP2_RO_ACTIVE_HIGH flag as indicator if GPIO line is to be
inverted compared to DT/platform-specified polarity. The flag is not used
after init in GPIO mode anyway. No functional changes intended.
