[U-Boot] [PATCH v2] clk: at91: Fix at91-pmc and at91-sckc's class ID

[Wenyou Yang]

The at91-pmc and at91-sckc aren't the clock providers, change their
class ID from UCLASS_CLK to UCLASS_SIMPLE_BUS, they also don't
need to bind the child nodes explicitly, the .post_bind callback
of simple_bus uclass will do it for them.
