Add the clock ops for such as spi0_clk, which is the real clock
provider, instead of periph32ck, which only recursively bind its
children as clk devices. Also update the clocks called in the
drivers.

Changes in v2:
 - Add Acked-by tag.
 - For the periph32ck, periph64ck, gck, systemck nodes, they aren't
   the clock providers, are to house various actual clock providers,
   use UCLASS_MISC, instead of UCLASS_CLK.
 - For *_of_xlate(), add argument check.
 - Fix the implementation of the *_get_rate().
 - Use documentation-wise variables for *_clk_probe().
 - Remove the duplicated code, use the common functions.
 - Add Acked-by tag for gpio/atmel_pio4.
