Commit 32f18e596141 ("mmc: improve API to make clear hw_reset callback is for cards") made it clear that the hw_reset callback is intended for resetting the card. Remove the .card_hw_reset callback from the meson-mx-sdhc-mmc driver because it's purpose is to reset the SDHC controller (FIFOs, PHY, DMA interface, ...). While here also rename and change the argument of meson_mx_sdhc_hw_reset so it cannot be called by accident as a replacement for card_hw_reset in the future.
