Fix incorrect earlycon option that should be xenboot instead of xen.
Refer:
https://elixir.bootlin.com/linux/v6.15.6/source/drivers/tty/hvc/hvc_xen.c#L772

Fix incorrect earlyprintk option. On Arm32 (Arm64 does not have
earlyprintk), it should be just earlyprintk which will enable compiled
in (if at all) debug printk code.
