cxgbe(4): Update T5 and T4 firmwares to 1.15.28.0.

These firmwares were obtained from the beta "Chelsio T5/T4 Unified Wire
v2.12.0.2 for Linux" release.  Changes since last release are listed in the
"Release Notes" accompanying the beta release and are copy-pasted here as well.

The plan is to have only GA'd firmwares in any -STABLE FreeBSD branch so I'll
MFC this (after 2 months) only if it ends up in a GA release.
