  Move cpu_feature_table array from arch specific rte_cpuflags.h files to
new arch specific rte_cpuflags.c files.

Main motivation is to escape from static variable declarations in
header files. cpu_feature_table has many copies in final binary, even
exist in some object files that does not use this variable at all.

And this can be a sample to create architecture specific source files
and move some functions which are not performance sensitive from
architecture header files to source files.

v2:
* rebased for DPDK2.3 (16.04)
* added arm arch
* renamed cpu_feature_table[] to rte_cpu_feature_table[]

Applied, thanks.

Now that we have some .c files for rte_cpuflags, I think some code
may be changed.
The function rte_cpu_get_features() and the struct feature_entry are
really specific to each arch and used only by rte_cpu_get_flag_enabled().
So they can be moved in .c and be more specific (leaf/subleaf is unused
for some archs).
Then there is no reason to keep rte_cpu_get_flag_enabled() inline.
