After "ARM: vexpress: Make the debug UART detection more specific",
building allyesconfig in linux-next now gives me:

arch/arm/kernel/debug.S: Assembler messages:
arch/arm/kernel/debug.S:81: Error: selected processor does not support ARM mode `movw r2,#0xc 091'
arch/arm/kernel/debug.S:81: Error: selected processor does not support ARM mode `movt r2,#0x4 10f'

Since the code can never get executed on ARMv6 but might
be built in a configuration that has ARMv6 enabled, it's
safe to just mark it in the assembly source for being
ARMv7-only.

Base the UART detection heuristic on architecturally defined
MIDR register instead of implementation dependent CBAR. The
only tile using the original memory map is V2P-CA9 with Cortex
A9 r0p1, which MIDR contains value 0x410fc091.

Move vexpress debug-macro.S over to common debug macro directory.
