xen/arm: Allow secondary cpus to start in THUMB

Unlike bx, eret will not update the instruction set (THUMB,ARM) according to
the return address. This will result to an unpredicable behaviour for the
processor if the address doesn't match the right instruction set.

When the kernel is compiled with THUMB2, THUMB bit needs to be set in CPSR
for the secondary cpus.
