[PATCH] xen/arm: Set ThumbEE as not present in PFR0

[Bertrand Marquis]

Force ThumbEE support to not available in the version of the PFR0
register value we present to guest.
Xen does not support ThumbEE and will trap all access to ThumbEE
registers so do not report it being supported if the hardware supports
it.

Fixes: 5bbe1fe413f9 ("ARM: Drop ThumbEE support")
