Amit Pundir reports that audio and USB-C host mode stops working if the
gcc_usb30_prim_master_clk_src clk is registered and
clk_rcg2_shared_init() parks it on XO. Skip parking this clk at
registration time to fix those issues.

Partially revert commit 01a0a6cc ("clk: qcom: Park shared RCGs upon
registration") by skipping the parking bit for this clk, but keep the
part where we cache the config register. That's still necessary to
figure out the true parent of the clk at registration time.

Fixes: 01a0a6cc ("clk: qcom: Park shared RCGs upon registration")
Fixes: 929c75d5 ("clk: qcom: gcc-sm8550: Mark RCGs shared where applicable")
