xen: arm: more flexible scheme for specifying early printk device

This allows for early-printk to be specified (for existing UARTS at
least) without the need to edit Rules.mk.

The existing shortcuts are retained, but in a much more compact
fashion.

An unused EARLY_PRINTK_BAUD was removed from the zynqmq settings.
