clk: renesas: rzg2l: Trust value returned by hardware
The onitial value of the CPG_PL2SDHI_DSEL bits 0..1 or 4..6 is 01b. The
hardware user's manual (r01uh0914ej0130-rzg2l-rzg2lc.pdf) specifies that
setting 0 is prohibited. Hence rzg2l_cpg_sd_clk_mux_get_parent() should
just read CPG_PL2SDHI_DSEL, trust the value, and return the proper clock
parent index based on the value read.
