ARM: pxa: ssp: Check return values from phandle lookups
Commit a6e56c28a178cef5f (ARM: pxa: ssp: add DT bindings) causes warnings
when built:
arch/arm/plat-pxa/ssp.c: In function 'pxa_ssp_probe':
arch/arm/plat-pxa/ssp.c:145:17: warning: 'dma_spec.args[0]' may be used
uninitialized in this function [-Wmaybe-uninitialized]
Resolve by checking return values and aborting when lookups fail.
