mmc_of_parse() for a few years has been using device property API.
Convert mmc_of_parse_voltage() as well.
At the same time switch users to new API.

When voltage-ranges property is not present the driver assumes that
it is 3.3v (3.2v..3.4v). But at the same time it disallows polling.
Fix that by dropping the comparison to 0 when no property is provided.
While at it, mark voltage-ranges property optional as it was initially.
Fixes: 9c43df57910b ("mmc_spi: Add support for OpenFirmware bindings")

SPI core already parses and maps IRQ for us if provided.
Use it instead of double parsing in mmc_spi_get_pdata().
Due to above, change condition, since SPI core can hold
an error pointer as invalid IRQ.
