[ARM] Remove MT_DEVICE_IXP2000 and associated definitions
As of the previous commit, MT_DEVICE_IXP2000 encodes to the same PTE bit encoding as MT_DEVICE, so it's now redundant. Convert MT_DEVICE_IXP2000 to use MT_DEVICE instead, and remove its aliases. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
