In general, the logic voltage is affected by ddr frequency factors.
We should fix the correct voltage range since assuemd that we have the
ddr frequency driver in mainline in the future.
AFAIK, the 1.8v voltage is used by the SD3.0 card.

Rk3288-evb-act8846 and rk3288-evb-rk808 are the power boards of
rk3288-evb, they provide the same power supply interface to the
motherboard. Sort out them, put the public part to rk3288-evb.dtsi,
such as gmac and cpu-supply, leaving only the power section.

According to the schematic, the name of REG8 should be vcc_tp, rather
than vcca_tp.

GPLv2-only devicetrees make reuse difficult for software components licensed
under a different license.
The consensus is that a GPL/X11 dual-license should allow all necessary uses,
so relicense the rk3288-evb files to this combination.
CCs were aquired by git shortlog -sne so it should've hopefully catched
every contributor.

This adds the static vcc_sys regulator to the rk3288-evb, the missing
rk808 supplies from it and all the supplies of the act8846 evb-variant.

Use the same transfer speed on both the rk808 and act8846 variants and
remove the status=okay from the rk808 one which is already set in the
shared rk3288-evb.dtsi .

The evaluation board using the act8846 as main pmic uses two additional
regulators to provide the cpu and gpu voltage. Add these and also add
the link to cpu supply from vdd_cpu.

The PMIC interrupt pinctrl line was added to the rk3288-evb-act8846,
but it's the same line on both the ACT8846 version and the RK808
version. This makes a lot of sense since they share the same SoC
daugherboard. Move the pinctrl definition to the common file so we
can use it for the RK808 version.
NOTE: The PMIC interrupt doesn't _actually_ go to the PMIC on the
ACT8846 version of the board (it does on the RK808), but our
convention is to label things as they're labelled on the schematics.
In the very least you can argue that this is the interrupt from the
PMIC daughtercard even if it doesn't actually go to the PMIC chip.

There exist 2 variants using either the act8846 or rk808 as pmic, while the
rest of the board stays the same.
