mmc: sdhci-of-at91: fix CALCR register being rewritten
When enabling calibration at reset, the CALCR register was completely
rewritten. This may cause certain bits being deleted unintentedly.
Fix by issuing a read-modify-write operation.
Fixes: 727d836a375a ("mmc: sdhci-of-at91: add DT property to enable calibration on full reset")
