octeontx2-pf: cn10k: Use runtime allocated LMTLINE region
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.
