Hi,

This patch moves the various tuning parameter data structures
further up config/aarch64/aarch64.c and then uses them to
initialise the generic_tunings variable. This mirrors their
position on trunk.

This fixes the warning:

config/aarch64/aarch64.c:129:33: warning: uninitialised const ‘generic_tunings’ is invalid in C++ [-Wc++-compat]

Regression tested on aarch64-none-elf with no regressions.

OK for aarch64-4.7-branch?

Thanks,
James
