Since the merge of the Mali dt bindings at [1], add support for Mali clocks
and DT node.
The Mali is clocked by two identical clock paths behind a glitch free mux
to safely change frequency while running.
So these clocks must be added to the meson-gxbb clock controller.
Changes since v3 at [7] :
- Removed CLK_IGNORE_UNUSED on mali clocks
Changes since v2 at [5] :
- Rebased on v2 Audio Clocks patchset from Jerome Brunet at [6]
- Marked parents names list as static
- Reworded patch 3 commit message
Changes since v1 at [2] :
- Remove GP0 fixes, this will pushed later, for base frequency it can depend on fclk_div3
- Add GXL support
- rebase on clk-next and jbrunet's patchset at [3] and [4]
- get rid of composite clocks, this adds more clocks IDs and exposes 2 more clocks

The Mali is clocked by two identical clock paths behind a glitch free mux
to safely change frequency while running.
The two "mali_0" and "mali_1" clocks are composed of a mux, divider and gate.
Expose these two clocks trees using generic clocks.
Finally the glitch free mux is added as "mali" clock.

The same MALI-450 MP3 GPU is present in the GXBB and GXL SoCs.
The node is simply added in the meson-gxbb.dtsi file.
For GXL, since a lot is shared with the GXM that has a MALI-T820 IP, this
patch adds a new meson-gxl-mali.dtsi and is included in the SoC specific
dtsi files.

LGTM, I can apply this when the clk driver changes are merged (feel free
to let me know when that happens, in case I'm not paying attention.)
<bikeshed>
nit: This series (and previous ones) use MALI, but I believe the correct
way is Mali. Could you standarize on that throughout the series?
</bikeshed>
