Workaround for Cortex A76 erratum 1800710

Cortex A76 erratum 1800710 is a Cat B erratum, present in older
revisions of the Cortex A76 processor core.  The workaround is to
set a bit in the ECTLR_EL1 system register, which disables allocation
of splintered pages in the L2 TLB.

This errata is explained in this SDEN:
