Subject: [PATCH v2 1/4] arm64: make rodata=on behaviour be the original rodata=full

Make rodata=on behaviour be the original rodata=full.
After this patch, the rodata=on will be the default,
and the arm64 kernel behaviour will follow the
Documentation/admin-guide/kernel-parameters.txt:
	rodata=		[KNL,EARLY]
		on	Mark read-only kernel memory as read-only (default).
