brcm47xx: add mips74k subtarget for newer devices

All new devices (with MIPS 74K CPU) are based on BCMA SoC and have
Ethernet core supported by bgmac. Create a new subtarget to generate
optimized builds.
This is just a beginning, further tweaks (like kernel configuration)
are still possible. This decreases default root.squashfs by ~128 kB.
