Subject: cerfpda ram cacheability

Hello

the cerfpda maps its DRAM as not cacheable. I'm not sure if it's by accident
or some problems were perceived if cache was enabled. Anyway this patch makes
RAM cacheable and for tm_basic at least performance is two orders of magnitude
better. Also for network benchmarks throughput is 3 times bigger.
Also I removed the second definition of the phys_to_virt macro from plf_mmap,h
because the macro was duplicated, and I kept the one hich matches virt_to_phys.
