crypto: octeontx2 - add support to map LMTST region for CN10K
On CN10K platform transmit/receive buffer alloc and free from/to
hardware had changed to support burst operation. Whereas pervious
silicon's only support single buffer free at a time.
To Support the same firmware allocates a DRAM region for each PF/VF for
storing LMTLINES. These LMTLINES are used to send CPT commands to HW.
PF/VF LMTST region is accessed via BAR4. PFs LMTST region is followed
by its VFs mbox memory. The size of region varies from 2KB to 256KB
based on number of LMTLINES configured.
This patch adds support for mapping of PF/VF LMTST region.
