9abbaa9539 build: remove MIPS dsp/dsp2 CPU_SUBTYPE
There does not seem to be any meaningful difference in generated code.
This will save some time and space on snapshot builds

c8eed9a50a brcm47xx: explicitly select CPU_MIPS32_R2 and CPU_MIPSR2 for mips74k
The mips74k subtarget of brcm47xx configures gcc to compile for mips32r2;
however, the generated kernel config for 3.14 and later kernels ends up
with CPU_MIPS32_R1 and CPU_MIPSR1 selected.  The generated kernel config
for the 3.10 kernel (Barrier Breaker) properly selected CPU_MIPS32_R2 and
CPU_MIPSR2.  Modify the default kernel config for mips74k to explicitly
select CPU_MIPS32_R2 and CPU_MIPSR2.

ed7c73fbef brcm47xx: activate some compiler optimizations for 74K CPUs
With this patch the mips74k subtarget will be compiled with optimized
compiler options to generated smaller and faster code. This currently
breaks broadcom-wl, because the binary blob is only compiled with
mipsr1 support.

bffd80e3e1 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.
