mlxsw driver will use NAPI for event processing in a next patch set.
Some additional improvements will be added later. This patch set
prepares the code for NAPI usage and refactor some relevant areas. See
more details in commit messages.

Patch Set overview:
Patches #1-#2 are preparations for patch #3
Patch #3 setups tasklets as part of queue initializtion
Patch #4 removes handling of unlikely scenario
Patch #5 removes unused counters
Patch #6 makes style change in mlxsw_pci_eq_tasklet()
Patch #7-#10 poll command interface instead of EQ0 usage
Patches #11-#12 make style change and break the function
mlxsw_pci_cq_tasklet()
Patches #13-#14 remove functions which can be replaced by a stored value
Patch #15 improves accessing to descriptor queue instance
