arm64: kernel: compiling issue, need delete read_current_timer()
Under arm64, we will calibrate the delay loop statically using a known
timer frequency, so delete read_current_timer(), or it will cause
compiling issue with allmodconfig.
The related error:
ERROR: "read_current_timer" [lib/rbtree_test.ko] undefined!
ERROR: "read_current_timer" [lib/interval_tree_test.ko] undefined!
ERROR: "read_current_timer" [fs/ext4/ext4.ko] undefined!
