Some RCGs could have sources with dynamic frequencies and fixed sources
where if the RCG has the flag of CLK_SET_RATE_PARENT set, it would try to
propagate the clock rate to the fixed source PLLs too. To identify sources
of the RCGs where the rate should propagate to parent PLL, add a member in
freq_tbl to represent source frequency. This would be used by the
_freq_tbl_determine_rate to set its parent frequency on the PLL.

In certain cases, it is desirable for an RCG to be turned on
explicitly instead of just relying on the enable signal from
its branch clock(s). Add support for this.

In certain cases, an RCG might be prone to being enabled even
though the overlying software thinks that it disabled the RCG.
In order to avoid letting the RCG go into an invalid state, support
parking it at a safe frequency during clk_disable() and deferring
all the RCG configuration updates to be done during clk_enable(),
if a scaling request comes in whilst the clock is disabled.

The sequence for alpha_pll_lucid_prepare is checking an incorrect bit
to determine whether or not a lucid PLL has calibrated successfully.
The bit in the status register is not observable unless pll_test_ctl[69]
is set and user_ctl[43:37] is 0 which should only be used as a fallback
option. Use the correct PCAL_DONE bit from the mode register to properly
determine PLL calibration status.

Some instances of the Zonda PLL do not lock correctly
in high L-VAL regions. In such cases, CFA mode
can be configured via test_ctl_val to use an alternative
locking mechanism. Add support for CFA mode by
polling FREQ_LOCK_DET instead of PLL_DET_LOCK
whenever CFA mode has been configured.

There are different configurations of display panels which may
or may not enable display PLLs before the display driver probes. Due to
continuous splash use cases, we may trample over existing PLL
configuration and cause the PLL to reset while it's in use. Prevent that
scenario by skipping the PLL configuration step if it's enabled.

Add a default send timeout for kernel qmi sockets. If a remote proc
crashes, there is a chance that the before shutdown cleanup will try
to send messages to the remote processor. When enough messages are
sent to a single port, the qrtr flow control will kick in and the QMI
socket will block indefinitly. Set the timeout to 10 seconds which
should be long enough to not affect normal functionality.
