ARM: mvebu: fix Cortex-A9 errata selection for Armada 38x
Armada 38x uses Cortex-A9 r4p1, but MACH_ARMADA_38X selects the
workaround for erratum 720789, which was fixed in r2p0, and omits
workarounds for errata that still affect r4p1.
Drop ARM_ERRATA_720789 and select ARM_ERRATA_754322 for faulty MMU
translations following an ASID switch and ARM_ERRATA_764319 for
unexpected undefined instruction exceptions when reading debug
registers. Also select ARM_ERRATA_764369 when SMP is enabled to work
around cache maintenance by MVA failing to reach other agents.
The Cortex-A9 r4 Software Developers Errata Notice (ARM UAN 0009D)
lists these errata in sections 2.3.3, 2.5.10 and 2.3.4, respectively.
