spi: spi-mtk-nor: Don't leak SPI master in probe error path

If the call to devm_spi_register_controller() fails on probe of the
MediaTek SPI NOR driver, the spi_controller struct is erroneously not
freed.

Since commit a1daaa991ed1 ("spi: spi-mtk-nor: use dma_alloc_coherent()
for bounce buffer"), the same happens if the call to
dmam_alloc_coherent() fails.

Since commit 3bfd9103c7af ("spi: spi-mtk-nor: Add power management
support"), the same happens if the call to mtk_nor_enable_clk() fails.

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