[PATCH v2 0/6] aarch64: Add FP8 multiplication instructions

[Andrew Carlotti]

This series is functionally identical to the previous FP8 multiplication series
and the "Enable gating instructions with FEAT_X || FEAT_Y" patch combined.  The
only change compared to the previous versions of these patches is in the
feature handling code, which is rewritten to use a new approach following a
conversation with Richard Earnshaw.

Are these ok for master?
