This patch checks the return value of imx_sc_misc_set_control() called
in dprc_prg_sel_configure() and generates warning dmesg in case the
return value is nonzero. The check makes Coverity happy.
This fixes Coverity issue: CID 10836597.

Instead of getting scu ipc handle from time to time in helpers
of the driver, we can get it in ->probe() once and cache it in
struct dprc. Also, we should check the return value of
imx_scu_get_handle() to get the handle in case it returns error
code. This makes Coverity happy.
This fixes two Coverity issues: CID 9993376 & CID 9993377.
