[PATCH] spi: sun4i: disable clocks in the remove function

mclk and hclk need to be disabled since pm_runtime_disable does
not disable the clocks.

Found by Linux Driver Verification project (linuxtesting.org).

Signed-off-by: Takuo Koguchi <takuo.koguchi.sw@xxxxxxxxxxx>
 V2: use pm_runtime_force_suspend to avoid unbalance disable
     Compile test only, no runtime test.
