For clarity it would be nice to factor cpucap manipulation out of <asm/cpufeature.h>, and the obvious place would be <asm/cpucap.h>, but this will clash somewhat with <generated/asm/cpucaps.h>. Rename <generated/asm/cpucaps.h> to <generated/asm/cpucap-defs.h>, matching what we do for <generated/asm/sysreg-defs.h>, and introduce a new <asm/cpucaps.h> which includes the generated header. Subsequent patches will fill out <asm/cpucaps.h>. There should be no functional change as a result of this patch.
