[Qemu-devel] [PULL 01/51] target-arm: Split out private-to-target functions into internals.h

[Peter Maydell]

Currently cpu.h defines a mixture of functions and types needed by
the rest of QEMU and those needed only by files within target-arm/.
Split the latter out into a new header so they aren't needlessly
exposed further than required.
