Subject: [PATCH v2 0/3] clk: meson: add support for Amlogic G12B

The Amlogic G12B SoC is very similar with the G12A SoC, sharing
most of the features and architecture.
G12B clock tree is very close, the main differences are :
- SYS_PLL is used for the second cluster (otherwise used fir the first on G12a)
- SYS_PLL1 is used for the first cluster (instead of SYS_PLL on G12a)
- A duplicate CPU tree is added for the second cluster
- G12B has additional clocks like for CSI an other components, not handled yet

Dependencies :
- Patch 1, 3 : None
- Patch 2 : Depends on Guillaume's Temperature sensor Clock patches at [1]

This patchset is a spinoff of the v2 Odroid-N2 megapatchset at [2]

Changes since v1 at [3]:
- Added the cpub_clk div2..8 and replaces the ahb/atb/axi/trace divs by muxes
- Added the CLK_GATE_SET_TO_DISABLE flag to ahb/atb/axi/trace gates
- Fixed all the G12A typos
- Added martin's reviewed by on patch 1

Changes since original patchset :
- Added missing sys1_pll div16, cpub div16 and cpub atb/axi/ahb/trace clocks
- Rewrote "This patch .." in commit messages
