mmc: core: Move mmc_of_parse_voltage() to host.c
MMC OF parsing functions, which parses various host DT properties, should stay close to each other. Therefore, let's move mmc_of_parse_voltage() close to mmc_of_parse() into host.c. Additionally, there is no reason to build the code only when CONFIG_OF is set, as there should be stub functions for the OF helpers that is being used, so let's drop this condition as well.
