To use the clock reset function easier, we implement the of_xlate.
This function is only adopted in version MTK_SET_CLR because of
the method of id calculation.

There is no impact for original use. If the argument number is not
larger than 1, it will return original id.

With this implementation if we want to set offset 0x120 and bit 16,
we can just write something like "resets = <&infra_rst 0x120 16>;".
