[PATCH][AARCH64]Clarify the usage of SCHED in AARCH64_CORE macro

[Renlin Li]

Hi all,

This is a simple patch to change a few misused IDNET in AARCH64_CORE to 
SCHED to reflect their original intentions.
The third argument of AARCH64_CORE macro is scheduler identity.

No functional change. aarch64-none-elf has been built and checked, no issue.
Okay for trunk?

Regards,
Renlin Li
