spi/rockchip: Make sure spi clk is on in rockchip_spi_set_cs
commit b920cc3191d7612f26f36ee494e05b5ffd9044c0 upstream.
Rockchip_spi_set_cs could be called by spi_setup, but
spi_setup may be called by device driver after runtime suspend.
Then the spi clock is closed, rockchip_spi_set_cs may access the
spi registers, which causes cpu block in some socs.
