Hi all:

As we know, the Loongson-2K family of SoCs (ls2k0500/ls2k1000/ls2k2000)
have a similar clock structure, and I support them to be configured with
different parameters (e.g., register offsets, etc.).

To make it easier to add support for different SoCs, I refactored the
original driver to make the whole driver as understandable as possible.

Briefly, I have divided all clocks into three categories according to
their properties and their parent clocks: Independent PLLs, clocks based
on frequency scales, and clock dividers.

Thanks.

----
V2:
patch(1/8):
 - Drop LOONGSON2_CLK_END, for it is not a binding.
patch(1/8)(3/8)(5/8):
 - Add Acked-by tag from Conor, Thanks.
