fix(st-sdmmc2): check regulator enable/disable return

The issue was reported by Coverity [1]. The return of the functions
regulator_disable() and regulator_enable() was not checked.
If they fail, this means there is an issue either with PMIC or I2C.
The board should the stop booting with a panic().

fix(ufs): delete call to inv_dcache_range for utrd

The utrd struct is allocated on the stack by ufs_check_resp's caller.
Invalidating the utrd struct is unnecessary since it's only read from,
and can cause other values stored on the stack (e.g. link register) to
be inadvertently invalidated.

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.
