There are many regulators are missed in previous commit, this
commit complete most of them. It also fix some mistakes in the
regulator properties. The VDD_10(REG10) and VCC_18(REG11) had better
to keep in always-on state, as it is used as the USB PHY supply,
corretly we have no way to assign power supply to a USB PHY.
The VCCA_33(REG8) should be enabled or the GMAC won't work.
It also fix the wrong properties for audio in io-domains, the supply
connected to APIO4_VDD is different to firefly release version.
