mtd: spi-nor: hisi-sfc: Remove excessive clk_disable_unprepare()
[ Upstream commit 78e4d342187625585932bb437ec26e1060f7fc6f ]
hisi_spi_nor_probe() invokes clk_disable_unprepare() on all paths after
successful call of clk_prepare_enable(). Besides, the clock is enabled by
hispi_spi_nor_prep() and disabled by hispi_spi_nor_unprep(). So at remove
time it is not possible to have the clock enabled. The patch removes
excessive clk_disable_unprepare() from hisi_spi_nor_remove().
Found by Linux Driver Verification project (linuxtesting.org).
