The (removed) pxa timer code (specifically __udelay()) could deadlock at

pxa: Fix boot hang by avoiding vector relocation

Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors")
pxa does not boot anymore.

Add a specific relocate_vectors macro that skips the vector relocation,
as the pxa SoC does not provide RAM at the high vectors address
(0xFFFF0000), and (0x00000000) maps to ROM.

This allows pxa to boot again.
