xen_blkbk_{map/unmap} in order to be able to map/unmap a random amount

Remove the last dependency from blkbk by moving the list of free

Check for the presence of PSCI before setting smp_ops, use PSCI if it is
available.
This is useful because at least when running on Xen it's possible to have a
PSCI node for example on a Versatile Express or an Exynos5 machine. In these
cases the PSCI SMP calls should be the ones to be called.
