[dpdk-dev] [PATCH v1 01/30] bus/dpaa: fix DPAA SEC blacklist case

[Sachin Saxena <sachin.saxena@nxp.com>]

From: Hemant Agrawal <hemant.agrawal@nxp.com>

The black list of dpaa_sec devices fails.
EAL: failed to parse device "dpaa:dpaa_sec-1"

This patch address following issues:
- bus usages dpaa-sec while the driver usage dpaa_sec
- bus usages numbers from 0 to MAX_SEC - while driver
probe usages sec number form max-fman_device +1

Fixes: 6e0752205bb2 ("bus/dpaa: support device blacklisting")
