Prathu Baronia 56b77ba112 arm64/cpucaps: increase string width to properly format cpucaps.h
The lengthiest capability is `WORKAROUND_TRBE_OVERWRITE_FILL_MODE` and
its length is 35 characters so increase the width of left justified
strings to 40 and adjust the tab space for `ARM64_NCAPS` accordingly.
Now the generated cpucaps.h is properly formatted.
