arm64: Factor out cpucap definitions
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.
