[PATCH v2 46/47] bus/fslmc: reduce probe-time logging and MC traffic

[Prashant Gupta <prashant.gupta_3@nxp.com>]

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

Every DMA map logged its virtual, IOVA and physical addresses at NOTICE.
An application that maps many memory segments prints one such line per
segment during initialisation, which drowns out messages the operator
actually needs; the neighbouring mapping paths already use debug level.

fslmc_vfio_get_bus_info() also issued mc_get_soc_version() twice in a row
into the same structure, so the second command only overwrote the first
result with an identical one. Keep a single query.
