[PATCH] spi: amlogic: spifc-a4: Remove redundant clock cleanup

[Felix Gu]

The driver uses devm_clk_get_enabled() which enables the clock and
registers a callback to automatically disable it when the device
is unbound.

Remove the redundant aml_sfc_disable_clk() call in the error paths
and remove callback.

Fixes: 4670db6f32e9 ("spi: amlogic: add driver for Amlogic SPI Flash Controller")
