spi: mxic: Don't leak SPI master in probe error path

commit cc53711b2191cf3b3210283ae89bf0abb98c70a3 upstream.

If the calls to devm_clk_get() or devm_ioremap_resource() fail on probe
of the Macronix SPI driver, the spi_master struct is erroneously not freed.

Fix by switching over to the new devm_spi_alloc_master() helper.
