powerpc: Move the testing of CPU_FTR_COHERENT_ICACHE into __flush_icache_range
In function flush_icache_range(), we use cpu_has_feature() to test
the feature bit of CPU_FTR_COHERENT_ICACHE. But this seems not optimal
for two reasons:
a) For ppc32, the function __flush_icache_range() already do this
check with the macro END_FTR_SECTION_IFSET.
b) Compare with the cpu_has_feature(), the method of using macro
END_FTR_SECTION_IFSET will not introduce any runtime overhead.
