spi: npcm-fiu: Don't leak SPI master in probe error path
If the calls to of_match_device(), of_alias_get_id(),
devm_ioremap_resource(), devm_regmap_init_mmio() or devm_clk_get()
fail on probe of the NPCM FIU SPI driver, the spi_controller struct is
erroneously not freed.
Fix by switching over to the new devm_spi_alloc_master() helper.
