Program SQ, MDQ, TL4 to TL2 transmit scheduler queues' DWRR
weight based on DWRR MTU programmed at NIX_AF_DWRR_RPM_MTU.
The DWRR MTU from admin function is retrieved via mbox.
On OcteaonTx2 silicon, admin function driver responds with DWRR
MTU as '1'. This helps to avoid silicon specific transmit
scheduler DWRR quantum/weight configuration logic.

The current driver uses static LMTST region allocated by firmware.
This memory gets populated as PF/VF BAR2. RVU PF/VF driver ioremap
the memory as device memory for NIX/NPA operation. Since the memory
is mapped as device memory we see performance degration. To address
this issue this patch implements runtime memory allocation.
RVU PF/VF allocates memory during device probe and share the base
address with RVU AF. RVU AF then configure the LMT MAP table
accordingly.

Add TC_MATCHALL ingress ratelimiting offload support with POLICE
action for entire traffic coming into the interface.
Eg: To ratelimit ingress traffic to 100Mbps
$ ethtool -K eth0 hw-tc-offload on
$ tc qdisc add dev eth0 clsact
$ tc filter add dev eth0 ingress matchall skip_sw \
action police rate 100Mbit burst 32Kbit
To support this, a leaf level bandwidth profile is allocated and all
RQs' contexts used by this interface are updated to point to it.
And the leaf level bandwidth profile is configured with user specified
rate and burst sizes.

This patch adds support to use new LMTST lines for NPA batch free
and burst SQE flush. Adds new dev_hw_ops structure to hold platform
specific functions and create new files cn10k.c and cn10k.h.
