[PATCH] arm64: fix for restoring console loglevel after handling traps

[hari.vyas@broadcom.com (Hari Vyas)]

changes in v1:
	Separate functions for changing, retrieving, storing and restoring
	console loglevel messages.
	Restoring console loglevel message is done from arm64 trap handling
	code but can be extended on need basis by other user.
	Restoring is actually required in die() function only and other places
	kernel will panic but added considering code completion
