Subject: [PATCH AUTOSEL 5.2 18/59] RDMA/qedr: Fix the hca_type and hca_rev returned in device attributes

From: Michal Kalderon <michal.kalderon@...vell.com>

[ Upstream commit 15fe6a8dcc3b48358c28e17b485fc837f9605ec4 ]

There was a place holder for hca_type and vendor was returned
in hca_rev. Fix the hca_rev to return the hw revision and fix
the hca_type to return an informative string representing the
hca.
