[PATCH 2/2] clk: versaclock: Fix internal crystal clock

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

When pin_xin does not exist and the chip supports an internal crystal,
we must create it. Do so, and don't try to enable an error pointer.

Fixes: dcf2cee77f2 ("clk: clk_versaclock: Add support for versaclock driver")
