[PATCH v7 03/16] drivers: add process-type guards for secondary process

[Hemant Agrawal]

From: Prashant Gupta <prashant.gupta_3 at nxp.com>

Add RTE_PROC_PRIMARY checks in device initialization paths for
net/dpaa, crypto/dpaa_sec and dma/dpaa drivers. Secondary
processes should skip hardware initialization to prevent
segfaults when accessing hardware registers that are only
mapped in the primary process.
