clk: qcom: dispcc-sm6350: Add missing parent_map for a clock
If a clk_rcg2 has a parent, it should also have parent_map defined,
otherwise we'll get a NULL pointer dereference when calling clk_set_rate
like the following:
[ 3.388105] Call trace:
[ 3.390664] qcom_find_src_index+0x3c/0x70 (P)
[ 3.395301] qcom_find_src_index+0x1c/0x70 (L)
[ 3.399934] _freq_tbl_determine_rate+0x48/0x100
[ 3.404753] clk_rcg2_determine_rate+0x1c/0x28
[ 3.409387] clk_core_determine_round_nolock+0x58/0xe4
[ 3.421414] clk_core_round_rate_nolock+0x48/0xfc
[ 3.432974] clk_core_round_rate_nolock+0xd0/0xfc
[ 3.444483] clk_core_set_rate_nolock+0x8c/0x300
[ 3.455886] clk_set_rate+0x38/0x14c
Add the parent_map property for the clock where it's missing and also
un-inline the parent_data as well to keep the matching parent_map and
parent_data together.
