[dpdk-dev] [PATCH 16/28] net/bnxt: use eal I/O device memory read/write API

[Jerin Jacob]

From: Santosh Shukla <santosh.shukla at caviumnetworks.com>

Replace the raw I/O device memory read/write access with eal abstraction
for I/O device memory read/write access to fix portability issues across
different architectures.
