[PATCH v3 16/19] ARM: dts: microchip: sama7g5: Add OTPC clocks

[Alexander Dahl]

These clocks should be enabled, datasheet says:

> The OTPC is clocked through the Power Management Controller (PMC).
> The user must power on the main RC oscillator and enable the
> peripheral clock of the OTPC prior to reading or writing the OTP
> memory.

Earlier discussions suggest, MCK0 must be enabled, too.  MCK0 is parent
of peripheral otpc_clk, so this is done implicitly.

    - new patch, not present in v1
