mmc: msm_sdhci: Use mmc_of_parse for setting host_caps

Since the introduction of 'get_cd' callback in sdhci core,
dragonboard410c's MMC interface is broken. It turns out that 'get_cd'
callback checks for the host_caps for validating the chip select. And
since the msm_sdhci driver is not parsing the host_caps from DT, not
all of the cababilities are parsed properly. This results in the MMC
interfaces to be broken.

Hence, fix this by adding a call to 'mmc_of_parse' during driver probe.
