spi: sc18is602: Don't leak SPI master in probe error path
commit 5b8c88462d83331dacb48aeaec8388117fef82e0 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.
