arm64: Implement HAVE_LIVEPATCH
Allocate a task flag used to represent the patch pending state for the
task. When a livepatch is being loaded or unloaded, the livepatch code
uses this flag to select the proper version of a being patched kernel
functions to use for current task.
In arch/arm64/Kconfig, select HAVE_LIVEPATCH and include proper Kconfig.
