commit bb8175a8aa42d731a840cd474e348ac3367eb5a0
  ("mmc: sdhci: clarify DDR timing mode between SD-UHS and eMMC")
added MMC_DDR52 as eMMC's DDR mode to be distinguished from SD-UHS.

While the differentation may be useful, pxav3 SDHCI controller lacks
a corresponding check in its custom .set_uhs_signaling callback for
MMC_DDR52. This patch adds a new switch case for MMC_TIMING_MMC_DDR52
to MMC_TIMING_UHS_DDR50 case.
