[dpdk-dev] [PATCH v2] bus/ifpga: fix forcing optional devargs

[Ferruh Yigit <ferruh.yigit@intel.com>]

From: Andy Pei <andy.pei@intel.com>

Original driver requires users to input "afu_bts" args.
But driver can also work without an explicit "afu_bts" args.

Fixes: 05fa3d4a6539 ("bus/ifpga: add Intel FPGA bus library")
