clk: qcom: gcc-sdm845: Do not use shared clk_ops for QUPs
Similar to the earlier fixes meant for sm8x50 and x1e platforms,
we have to stop using the shared clk ops for sdm845 QUPs as well.
As Stephen Boyd pointed out in earlier fixes, there wasn't a problem
to mark QUP clks shared until we started parking shared RCGs at clk
registration time in commit 01a0a6cc8cfd ("clk: qcom: Park shared RCGs
upon registration"). Parking at init is actually harmful to the UART
when earlycon is used. If the device is pumping out data while the
frequency changes and we see garbage on the serial console until the
driver can probe and actually set a proper frequency.
This patch reverts the QUP clk sharing ops part of commit 06391eddb60a
("clk: qcom: Add Global Clock controller (GCC) driver for SDM845"), so
that the QUPs on sdm845 don't get parked during clk registration and
break UART operations.
