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.
