  clk: mediatek: mt7988-infracfg: fix clocks for 2nd PCIe port (2024-04-10 20:50:26 -0700)

----------------------------------------------------------------
A couple clk driver fixes, a build fix, and a deadlock fix.

 - Mediatek mt7988 has broken PCIe because the wrong parent is used

 - Mediatek clk drivers may deadlock when registering their clks because
   the clk provider device is repeatedly runtime PM resumed and
   suspended during probe and clk registration. Resuming the clk
   provider device deadlocks with an ABBA deadlock due to genpd_lock and
   the clk prepare_lock. The fix is to keep the device runtime resumed
   while registering clks.

 - Another runtime PM related deadlock, this time with disabling unused
   clks during late init. We get an ABBA deadlock where a device is
   runtime PM resuming (or suspending) while the disabling of unused
   clks is happening in parallel. That runtime PM action calls into the
   clk framework and tries to grab the clk prepare_lock while the
   disabling of unused clks holds the prepare_lock and is waiting for
   that runtime PM action to complete. The fix is to runtime resume all
   the clk provider devices before grabbing the clk prepare_lock during
   disable unused.

 - A build fix to provide an empty devm_clk_rate_exclusive_get()
   function when CONFIG_COMMON_CLK=n
