clk: qcom: gcc: Use active only source for CPUSS clocks

[ Upstream commit 9ff1a3b4912528f853048ccd9757ba6a2cc75557 ]

The clocks of the CPUSS such as "gcc_cpuss_ahb_clk_src" is a CRITICAL
clock and needs to vote on the active only source of XO, so as to keep
the vote as long as CPUSS is active. Similar rbcpr_clk_src is also has
the same requirement.
