Provide convenience links for BCM43455/CYW43455 based RPi3A+, RPi3B+ and RPi4B
WIFI firmware configuration files to avoid runtime firmware loading warning in
the kernel logs, e.g. (RPi3B+):

  brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.raspberrypi,3-model-b-plus.txt failed with error -2

or (RP4B

  brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt failed with error -2

Changes: 
  added links for brcmfmac43430 based boards RPi [0w, 3b]
