mmc: sdhci-of-at91: fix MMC_DDR_52 timing selection

commit d0918764c17b94c30bbb2619929b1719ff52707a upstream.

The controller has different timings for MMC_TIMING_UHS_DDR50 and
MMC_TIMING_MMC_DDR52. Configuring the controller with SDHCI_CTRL_UHS_DDR50,
when MMC_TIMING_MMC_DDR52 timings are requested, is not correct and can
lead to unexpected behavior.
