brcm47xx: add support for the kernel 4.19
One patch that wasn't ported due to a lot of conflict is:
901-Revert-bcma-switch-GPIO-portions-to-use-GPIOLIB_IRQC.patch
Hopefully a correct/real fix will get developed before we switch
brcm47xx to the 4.14.
This IS NOT ready for switching/trying/using 4.19 yet due to some DMA
regression affecting bgmac:
