spi: rb4xx: Don't leak SPI master in probe error path
commit a4729c3506c3eb1a6ca5c0289f4e7cafa4115065 upstream.
If the calls to devm_clk_get(), devm_spi_register_master() or
clk_prepare_enable() fail on probe of the Mikrotik RB4xx SPI driver,
the spi_master struct is erroneously not freed.
Fix by switching over to the new devm_spi_alloc_master() helper.
Fixes: 05aec357871f ("spi: Add SPI driver for Mikrotik RB4xx series boards")
