[PATCH v1 1/8] MT9M114: Add bypass-pll DT-binding

[Mathis Foerst]

The MT9M114 sensor has an internal PLL that generates the required SYSCLK
from EXTCLK. It also has the option to bypass the PLL and use EXTCLK
directly as SYSCLK.
The current driver implementation uses a hardcoded PLL configuration that
requires a specific EXTCLK frequency. Depending on the available clocks,
it can be desirable to use a different PLL configuration or to bypass it.

Add the 'bypass-pll' property to the MT9M114 DT-bindings to allow selecting
the PLL bypass mode.
