[PATCH 44/54] net/bnxt: truflow remove RTE devarg processing for mpc=1

[Manish Kurup]

From: Sangtani Parag Satishbhai <parag-satishbhai.sangtani at broadcom.com>

Now as the mpc is initialized for P7 platform regardless
of mpc=1 devarg, RTE and bnxt argument processing APIs
for mpc devarg are redundant. This patch removes such RTE
and bnxt APIs. The "mpc=1" devarg is now invalid and should
not be used while launching an application.

Before:
     ./dpdk-testpmd -c 0xff -a 0000:0a:00.0,mpc=1,app-id=0
After:
     ./dpdk-testpmd -c 0xff -a 0000:0a:00.0,app-id=0
