Mitchell Horne 3d89a9759f arm64: parse HWCAP values using user_cpu_desc
The hard work of parsing fields per-CPU, handling heterogeneous
features, and excluding features from userspace is already done by
update_special_regs. We can build our set of HWCAPs from the result.

This exposed a small bug in update_special_regs, in which the
generated bitmask was not wide enough, and as a result some bits
weren't being exposed in user_cpu_desc. Fix this.

While here, adjust some formatting.
