The eMMC HW reset may be implemented either via the host ops ->hw_reset() callback or through DT and the eMMC pwrseq. Additionally some eMMC cards don't support HW reset. To allow a reset to be done for the different combinations of mmc hosts and eMMC/MMC cards, let's implement a fallback via trying a regular power cycle. This improves the mmc block layer retry mechanism of failing I/O requests.
