feat(allwinner): allow to skip PMIC regulator setup

For somewhat historical reasons we are doing some initial PMIC regulator
setup in BL31, as U-Boot does not (yet) have a PMIC driver. This worked
fine so far, but there is at least one board (OrangePi 3) that gets upset,
because the Ethernet PHY needs some *coordinated* bringup of *two*
regulators.

To avoid custom hacks, let's introduce a build option to keep doing the
regulator setup in TF-A. Defining SUNXI_SETUP_REGULATORS to 0 will break
support for some devices on some boards in U-Boot (Ethernet and HDMI),
but will allow to bring up the OrangePi 3 in Linux correctly. We keep
the default at 1 to not change the behaviour for all other boards.

After U-Boot gained proper PMIC support at some point in the future, we
will probably change the default to 0, to get rid of the less optimal
PMIC code in TF-A.

Merge changes from topic "allwinner_pmic" into integration

* changes:
allwinner: h6: power: Switch to using the AXP driver
drivers: allwinner: axp: Add AXP805 support

drivers: allwinner: axp: Add AXP805 support

This adds the new regulator list, as well as changes to make the switch
(equivalent to DC1SW on the AXP803) work on both PMICs.
