spi: mt7621: Use devm_spi_register_controller()

Now that clk_disable_unprepare(clk) is handled with a managed resource,
we can use devm_spi_register_controller() and axe the .remove function.

The order between spi_unregister_controller() and clk_disable_unprepare()
is still the same.
(see commit 46b5c4fb87 ("spi: mt7621: Don't leak SPI master in probe
error path") to see why it matters)
