[PATCH v1 5/6] mmc: mmc_spi: Use already parsed IRQ

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

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.
