Mark Brown 863da0bdb1 arm64/cpufeature: Use helper macro to specify ID register for capabilites 
When defining which value to look for in a system register field we
currently manually specify the register, field shift, width and sign and
the value to look for. This opens the potential for error with for example
the wrong field width or sign being specified, an enumeration value for
a different similarly named field or letting something be initialised to 0.

Since we now generate defines for all the ID registers we now have named
constants for all of these things generated from the system register
description, meaning that we can generate initialisation for all the fields
used in matching from a minimal specification of register, field and match
value. This is both shorter and eliminates or makes build failures several
potential errors.

No change in the generated binary.
