I can reword to "For arm32, all the users of processor.h expects cpregs.h to be included in order to access co-processors.

Currently, cpregs.h is included in pretty much every files even for arm64. However, the only use for arm64 is when emulating co-processors. For arm32, cpregs.h rely on the presence of processor.h (define *_SYSREG helpers). So move the inclusion in asm-arm/arm32/processor.h. cpregs.h will also be directly included in the co-processors emulation to accomodate arm64.
