bsps/arm: Change code to explicit selection of cache implementation for ARM BSPs.
The original ARM architecture wide cache_.h is changed to dummy version
for targets not implementing/enablig cache at all.
The ARM targets equipped by cache should include
appropriate implementation.
Next options are available for now
c/src/lib/libbsp/arm/shared/armv467ar-basic-cache/cache_.h
basic ARM cache integrated on the CPU core directly
which requires only CP15 oparations
c/src/lib/libbsp/arm/shared/arm-l2c-310/cache_.h
support for case where ARM L2C-310 cache controller
is used. It is accessible as mmaped peripheral.
c/src/lib/libbsp/arm/shared/armv7m/include/cache_.h
Cortex-M specific cache support
