ARM: mvebu: Fix broken PL310_ERRATA_753970 selects

commit 8aa36a8dcde3183d84db7b0d622ffddcebb61077 upstream.

The MACH_ARMADA_375 and MACH_ARMADA_38X boards select ARM_ERRATA_753970,
but it was renamed to PL310_ERRATA_753970 by commit fa0ce403 ("ARM:
7162/1: errata: tidy up Kconfig options for PL310 errata workarounds").

Fix the selects to use the new name.

Discovered with the

script.
