[v2,0/3] Add clock controller support for Spacemit K1

Message

The clock tree of Spacemit K1 is managed by several independent
controllers in different SoC parts. In this series, all clock hardwares
in APBS, MPMU, APBC and APMU, are implemented. With some changes to UART
driver, CPU cores and UARTs could be brought up (see below). More clocks
will be implemented later soon.

No device tree changes are included since Spacemit K1 UART needs two
clocks to operate, but for now the driver gets only one. I would like to
defer the changes until this is resolved.

Tested on BananaPi-F3 board, a clock tree dump could be obtained here[1].

This series depends on

Changed from v1
- add SoC prefix (k1)
- relicense dt-binding header
- misc fixes and style improvements for dt-binding
- document spacemit,k1-syscon
- implement all APBS, MPMU, APBC and APMU clocks
- code cleanup
- Link to v1: https://lore.kernel.org/all/[e-mail]/
