zynq: do fixed mapping for ocm memory on boot and make kaddr() and paddr() work with it

map the whole ocm memory on boot so we can translate physical to
virtual addresses and back for uncached memory using KADDR() and
PADDR().

replace ualloc() with ucalloc() returning virtual address. physical
address can be acquired with PADDR() now.

as ocm is now always mapped, use KADDR() instead of tmpmap() for
mp bootstrap.
