[PATCH 28/45] drivers: identify dpaa2 soft parser protocol

[Prashant Gupta <prashant.gupta_3@nxp.com>]

From: Jun Yang <jun.yang@nxp.com>

Identify if soft parser protocol firmware is loaded by checking
firmware magic number.
Enable flow/parser of ECPRI, GENEVE, ROCEv2 and VXLAN's spec
only with soft parser protocol firmware being loaded.
