Our list of possible Allwinner build targets was missing the newly
introduced R329 support. Fix that by adding a table with maps the SoC
names to the build target names.
Also add some explanation about the recently introduced PSCI power
management providers.

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.

To correctly initialize the MMC devices, a power cycle is required.
For this we need to:
- disable vmmc-supply regulator
- make the power cycle required for SDMMC2 peripheral
- enable regulators

Store status of dt_pmic_status() as local static variable,
this avoids parsing DT several times.
In the same way, store nodes in dt_pmic_i2c_config() and
in dt_get_pmic_node() as local static variables.

In mt8186 suspend/resume flow, ATF has to communicate with a subsys by
read/write the subsys registers. However, the register region of subsys
doesn't include in the MMU mapping region. It triggers MMU faults.
This patch extends the MMU region 0 size to cover all mt8186 HW modules.
This patch also remove MMU region 1 because region 0 covers region 1.
