Add a new config CONFIG_CLK_AUTO_ID to support a unique clk id
for all the clock providers, managed by clk uclass, when the clock
reference arg[0] is the same.
When the CONFIG is activated, the clock id is limited to the lower
CLK_ID_SZ = 24 bits in default clock xlate function
and the sequence number + 1 of the clk provider device is
added for the 8 higher bits.
We use sequence number + 1 to avoid the "dummy" clock id = 0,
used for invalid clock when CCF is activated.
When this config is activated, the new function clk_get_id()
should be used to get back the internal reference to clock
for the each clock provider.
