SM8450, and SC8280XP gains a GPU clock controller.  MSM8909 and SM6375
gains global and SMD RPM clock controller drivers.

The handling of GDSCs with PWRSTS_RET was fixed, to keep the GDSC on
while powering down the parent supply. This solved retention issues
during suspend of USB on sc7180/7280 and SC8280XP.

SM6115 and QCM2260 are moved to reuse PLL configuration. SDM660 SDCC1
was moved to floor ops.

Support for the APCS PLLs for IPQ8064, IPQ8074 and IPQ6018 was
added/fixed. The MSM8996 CPU clocks was updated, with support for ACD
clocks added.

Support for SDM670 was added to the SDM845 Glbal clock controller and
the RPMh clock controller driver.

Transition to parent_data, parent_hws and use of ARRAY_SIZE() for
num_parents was done for MSM8660, MSM8916, MSM8939, MSM8960 global clock

clk: mediatek: mt8183: Add clk mux notifier for MFG mux

When the MFG PLL clock, which is upstream of the MFG clock, is changed,
the downstream clock and consumers need to be switched away from the PLL
over to a stable clock to avoid glitches.

This is done through the use of the newly added clk mux notifier. The
notifier is set on the mux itself instead of the upstream PLL, but in
practice this works, as the rate change notifitcations are propogated
throughout the sub-tree hanging off the PLL. Just before rate changes,
the MFG mux is temporarily and transparently switched to the 26 MHz
main crystal. After the rate change, the mux is switched back.

clk: mediatek: mux: add clk notifier functions

With device frequency scaling, the mux clock that (indirectly) feeds the
device selects between a dedicated PLL, and some other stable clocks.

When a clk rate change is requested, the (normally) upstream PLL is
reconfigured. It's possible for the clock output of the PLL to become
unstable during this process.

To avoid causing the device to glitch, the mux should temporarily be
switched over to another "stable" clock during the PLL rate change.
This is done with clk notifiers.

This patch adds common functions for notifiers to temporarily and
transparently reparent mux clocks.

This was loosely based on commit 8adfb08605a9 ("clk: sunxi-ng: mux: Add
