[PATCH v2 1/3] clk: spacemit: prepare common ccu header

[Yixun Lan]

In order to prepare adding clock driver for new SoC, extract common
ccu header file, so it can be shared by all drivers.

Also introduce a reset name macro, so it can be both used in clock
and reset subsystem, explicitly to make them match each other.
