bcm27xx: drop outdated kernel version switches from patches-5.4 

This drops some ancient kernel version switches from patches on
bcm27xx target. The patch only adjusts the latest kernel 5.4, as
doing it a second time for an older kernel seems a waste of time
for a cosmetic change.

Refresh remaining target patches.
