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 commit01a0a6cc8c("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 commit06391eddb6("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
