bcm47xx: add support for kernel 5.4
Ethernet, switch, LEDs, buttons, USB, sysupgrade & LuCI were successfully tested on BCM4706. WARNING: Hack for BCM4710 adding BCM4710_PROTECTED_FILL_TLB() to the local_r4k_flush_cache_sigtramp() could not be ported. That function has been dropped in: commit adcc81f148d7 ("MIPS: math-emu: Write-protect delay slot emulation pages") commit 3315b6b336c8 ("MIPS: Delete unused flush_cache_sigtramp()") it's unsure if that chipset will still work reliably.
