LF-2010 gpu: imx: imx8_dprc: Check return value of SCU func call in dprc_prg_sel_configure() 

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.
