[Qemu-devel] [PATCH] target-arm: Tidy up ARM1136 CPUID naming

["Andreas Färber" <andreas.faerber@web.de>]

-cpu arm1136-r2 is commented to in fact be ARM1136 r0p2, whereas
-cpu arm1136 seems to be ARM1136 r1p3 according to the MIDR value.

The CPUID values contain major and minor revision numbers (rnpn) and
are never used with a mask, so are specific to the chosen revision.
Rename the CPUID preprocessor defines to reflect this, but leave the
CPU model names unchanged for command line compatibility.
