6ffdc43cc5 clk: sunxi: add compatible string for V3
A new compatible string is introduced for V3 CCU, because it has a few
extra features available.

Add the compatible string to the clock driver. As the extra features are
not touched, just share the description struct now.

106c1300a5 sunxi: clocks: Add H6 USB clock gates and resets
To enable USB support in U-Boot, add the required clock and reset gates
to the H6 clock driver. Once enabled, the generic EHCI/OCHI drivers will
pick them up from there automatically.

33685372cf clk: sunxi: r40: Fix GMAC reset reg offset
GMAC reset reg offset added by below commit seems to assume
it as EMAC but R40 indeed using GMAC.
"clk: sunxi: Implement EMAC, GMAC clocks, resets"
(sha1: 68620c9698)

So, fix by updating the reg offset for RST_BUS_GMAC.

13b0867dc3 sunxi: clk: enable clk and reset for CCU devices
Some Allwinner clock devices have parent clocks and reset gates itself,
which need to be activated for them to work.

Add some code to just assert all resets and enable all clocks given.
This should enable the A80 MMC config clock, which requires both to be
activated. The full CCU devices typically don't require resets, and have
just fixed clocks as their parents. Since we treat both as optional and
enabling fixed clocks is a NOP, this works for all cases, without the need
to differentiate between those clock types.

e0c7ce7e52 sunxi: clk: A80: add MMC clock support
The A80 handles resets and clock gates for the MMC devices differently,
outside of the CCU IP block. Consequently we have a separate clock
device with a separate binding for that.

Implement that with the respective clock gates and resets to allow the
A80 taking part in the DM_MMC game.
