refactor(plat/allwinner): allow new AA64nAA32 position

In newer Allwiner SoCs, the AA64nAA32 wires are mapped to a new register
called "General Control Register0" in the manual rather than the
"Cluster 0 Control Register0" in older SoCs.

Now the position of AA64nAA32 (reg and bit offset) is defined in a few
macros instead assumed to be at bit offset 24 of
SUNXI_CPUCFG_CLS_CTRL_REG0.

fix(plat/marvell/a3k): disable HANDLE_EA_EL3_FIRST by default

fix(plat/marvell/a3k): disable HANDLE_EA_EL3_FIRST by default

It was enabled in commit 3c7dcdac5c50 ("marvell/a3700: Prevent SError
accessing PCIe link while it is down") with a workaround for a bug found
in U-Boot and Linux kernel driver pci-aardvark.c (PCIe controller driver
for Armada 37xx SoC) which results in SError interrupt caused by AXI
SLVERR on external access (syndrome 0xbf000002) and immediate kernel
panic.

Now when proper patches are in both U-Boot and Linux kernel projects,
this workaround in TF-A should not have to be enabled by default
anymore as it has unwanted side effects like propagating all external
aborts, including non-fatal/correctable into EL3 and making them as
fatal which cause immediate abort.

Add documentation for HANDLE_EA_EL3_FIRST build option into Marvell
Armada build section.

fix(plat/marvell/a3k): update information about PCIe abort hack

A3700 plat_ea_handler was introduced into TF-A codebase just because of
bugs in U-Boot and Linux kernel PCIe controller driver pci-aardvark.c.

These bugs were finally fixed in both U-Boot and Linux kernel drivers:
https://source.denx.de/u-boot/u-boot/-/commit/eccbd4ad8e4e182638eafbfb87ac139c04f24a01
https://git.kernel.org/stable/c/f18139966d072dab8e4398c95ce955a9742e04f7

Add all these information into comments, including printing error
message into a3k plat_ea_handler. Also check that abort is really
asynchronous and comes from lower level than EL3.
