Currently for each hwcap we define both the HWCAPn_NAME definition which is exposed to userspace and a kernel internal KERNEL_HWCAP_NAME definition which we use internally. This is tedious and repetitive, instead use a script to generate the KERNEL_HWCAP_ definitions from the UAPI definitions. No functional changes intended.
