Add support for counter allocation on router interfaces. The allocation
depends on the counter state of relevant table. In case the counting is
disabled or no counters left the counter index will be set as invalid.
Also a counter pool for router allocation is added.

Add support for allocating generic flow counter. Generic flow counter
can count packets or packets and bytes and can be assigned to different
hardware processes. First use will be for counting packets and bytes of

Add implementation for counter allocator. The ASIC has special memory
pool for various counting purposes. Counter memory is distributed between
equal size banks.
The static sub-pool configuration should specify the following parameters
for each sub-pool:
- Number of required banks.
- Maximum entry size.
Each module can add dedicated sub-pool or use existing one.
