LDWB is getting incorrectly used in HW when
CPT_AF_LF()_PTR_CTL[IQB_LDWB]=1 and CPT instruction queue has less than
320 free entries. So, increase HW instruction queue size by 320 and give
320 entries less for SW/NIX RX as a SW workaround.

CPT result format had changed for CN10K HW to accommodate more
fields. This patch adds support to use new result format and
new LMTST lines for CPT operations on CN10K platform.

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.

OcteonTX2 series of silicons have multiple variants, the
98xx variant has two crypto (CPT0 & CPT1) blocks. This patch
adds support for firmware load on new CPT block(CPT1).

CPT RVU Local Functions(LFs) needs to be attached to the
PF/VF to submit the instructions to CPT.
This patch adds the interface to initialize and attach
the LFs. It also adds interface to register the LF's
interrupts.
