mmc: am654_sdhci: Add MMC_HS_52 to timing data

Browse Source 
This patch adds MMC_HS_52 to the timing data structure.

Previously, this bus mode tap settings were not populated and
were instead populated for MMC_HS which is a different bus mode
up to 26MHz. Since we intended these settings according to the
device data sheet[0] for MMC_HS_52 up to 52MHz, populate MMC_HS
tap settings for MMC_HS_52.

While we are here, fix typo in ti,itap-del-sel-mms-hs.
