Currently, dwmac-rk uses a custom propety "phy_regulator" to get the name of the
right regulator to use to power on or power off the phy. This commit converts the
driver to use phy-supply devicetree property and the corresponding API, it cleans
the code a bit and make it simpler to maintain. This also replaces the property
phy_regulator by the standard property phy-supply in rk3288-evb-rk808.dts.

enable gmac in rk3288-evb-rk808.dts
changes since v2:
1. add fixed regulator for PHY
2. remove power-gpio, reset-gpio, phyirq-gpio, pmu_regulator setting
3. add "snps,reset-gpio", "snps,reset-active-low;" "snps,reset-delays-us"

This adds the cpu-supplies to the curie2, radxarock and rk3288-evb-rk808 boards.
The rk3288-evb-act8846 variant cannot provide the cpu-regulator at the moment
so will get its supply later.

We should be able to talk to the PMIC at 400kHz. No need to talk at
the slow 100kHz.
As measured by ftrace (with a bunch of extra patches, since cpufreq
for rk808 hasn't landed yet):
before this change: cpu0_set_target() => ~500us
after this change: cpu0_set_target() => ~300us

This adds initial support. For now, regulators are always on and we
don't specify the input supply for all of the regulators.

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