spi: sc18is602: Don't leak SPI master in probe error path
commit 5b8c884 upstream. If the call to devm_gpiod_get_optional() fails on probe of the NXP SC18IS602/603 SPI driver, the spi_master struct is erroneously not freed. Fix by switching over to the new devm_spi_alloc_master() helper. Fixes: f990080 ("spi: sc18is602: Add reset control via gpio pin.")
