Evgeny Novikov d2ff7a8b07 mtd: spi-nor: hisi-sfc: Remove excessive clk_disable_unprepare() ...

[ Upstream commit 78e4d34218 ]

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().
