Subject: [PATCH 0/2] Add clock controller support for Spacemit K1

The clock tree of Spacemit K1 is managed by several independent
controllers in different SoC parts. In this series, only all clock
hardwares in APBS and MPMU, and some in APBC and APMU, are implemented,
which is enough to bring up CPU cores and UARTs with some changes to
UART driver (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].
