Log Message:
Add a ARM_HAS_VBAR option which forces the use of the VBAR register. This
allows much code to deal with vector_page mappings to be eliminated. On a
BEAGLEBONE kernel, this saves 8KB of text and instructions that never have
to be executed. (The PJ4B has VBAR but doesn't implement the security
extensions it is part of so a method was needed to allow it use VBAR with
relying on the default test for the security extensions.)
