8a474d01ee Add accessors for the ARM CP15 performance monitor registers. Also ensure 
that some #ifdef SMP code is also conditional on __ARM_ARCH >= 7; we don't
support SMP on armv6, but some drivers and modules are compiled with it
forced on via the compiler command line.

54f9ec883d Define a WFI macro that expands to the right form of wait-for-interrupt 
depending on the architecture.

1af789ed11 Add machine/sysreg.h to simplify accessing the system control coprocessor 
registers and use it in the ARMv7 CPU functions.

The sysreg.h file has been checked by hand, however it may contain errors
with the comments on when a register was first introduced. The ARMv7 cpu
functions have been checked by compiling both the previous and this version
and comparing the md5 of the object files.
