[ARM] ARMv6: add CPU_HAS_ASID configuration
Presently, we check for the minimum ARM architecture that we're
building for to determine whether we need ASID support. This is
wrong - if we're going to support a range of CPUs which include
ARMv6 or higher, we need the ASID.
Convert the checks to use a new configuration symbol, and arrange
for ARMv6 and higher CPU entries to select it.
