[PATCH v2 1/3] dt-bindings: clock: fix C3 PLL input parameter

[Xianwei Zhao via B4 Relay <devnull+xianwei.zhao.amlogic.com@kernel.org>]

From: Xianwei Zhao <xianwei.zhao@amlogic.com>

Add C3 PLL controller input clock parameters "fix".

The clock named "fix" was initially implemented in PLL clock controller driver.
However, some registers required secure zone access, so we moved it to
the secure zone (BL31) and accessed it through SCMI. Since the PLL clock
driver needs to use this clock, the "fix" clock is used as an input source.
We updated the driver but forgot to modify the binding accordingly,
so we are adding it here.

It is an ABI break but on a new and immature platform.
Noboby could really use that platform at this stage, so nothing is going
to break on anyone really.
