For the peripheral clock, provide the clock ops for the clock
provider, such as spi0_clk. The .of_xlate is to get the clk->id,
the .enable is to enable the spi0 peripheral clock, the .get_rate
is to get the clock frequency.

The driver for periph32ck node is responsible for recursively
binding its children as clk devices, not provide the clock ops.

So do the generated clock and system clock.
