[PATCH, AArch64] Add configury files to the cpu-init subdir

[Yufeng Zhang]

Hi,

This patch adds configuration files to 'libgloss/aarch64/cpu-init'.  The 
'cpu-init' subdir previouly only had 'Makefile.in' and it relied on its 
parent's configuration file to config certain variables.

An issue had been identified that '@host_makefile_frag_path@' in 
'cpu-init/Makefile.in' may not get expanded correctly especially when 
'srcdir' is not an absolute path.

This patch fixes this issue by adding 'configure.in' and its friends to 
the 'cpu-init' subdir so that 'host_makefile_frag_path' can be set properly.

Is it OK to commit?


Thanks,
Yufeng
