Stefan Agner f84a8d446a spi: imx: do not access registers while clocks disabled ...

commit d593574aff upstream.

Since clocks are disabled except during message transfer clocks
are also disabled when spi_imx_remove gets called. Accessing
registers leads to a freeeze at least on a i.MX 6ULL. Enable
clocks before disabling accessing the MXC_CSPICTRL register.

Fixes: 9e556dcc55 ("spi: spi-imx: only enable the clocks when we start to transfer a message")
