[PATCH 1/2] clk: versaclock: Fix clk_get_rate

[Sean Anderson <sean.anderson@linux.dev>]

Devicetree clock references point at the main versaclock device. We
must determine the parent clock manually, as it depends on the clock id.
The device parent of the versaclock will generally be an I2C bus and not
another clock.
