BACKPORT: arm64: asm-offsets: remove unused definitions 



Subsequent patches will move the thread_info::{task,cpu} fields, and the
current TI_{TASK,CPU} offset definitions are not used anywhere.

This patch removes the redundant definitions.

check if CONFIG_THREAD_INFO_IN_TASK is used has been inserted.
