Introduce definitions of fields in CQE version 1 and 2. Also, introduce
common helpers that would call appropriate version-specific helpers
according to the version enum passed.

After performing reset driver polls on HW indication until learning
that the reset is done, but immediately after reset the device becomes
unresponsive which might lead to completion timeout on the first read.
Wait for 100ms before starting the polling.

The "trap_id" is 9bits long. So far, this was not a problem since we
used only traps with ids that fit into 8bits. But the ACL traps that are
going to be introduced use the 9th bit.

The event_data starts from address 0x00-0x0C and not from 0x08-0x014. This
leads to duplication with other fields in the Event Queue Element such as
sub-type, cqn and owner.

So far, mlxsw_pci.ko is the module that registers PCI table for all
drivers (spectrum and switchx2). That is problematic for example with
dracut. Since mlxsw_spectrum.ko and mlxsw_switchx2.ko are loaded
dynamically from within mlxsw_core.ko, dracut does not have track of
them and avoids them from being included in initramfs.
So make this in an ordinary way and define the PCI tables in individual
driver modules, so it can be properly loaded and included in dracut
initramfs image. As a side effect, this patch could remove no longer
necessary driver "kind" strings which were used to link PCI ids with
individual mlxsw drivers.

pci.h needs to be used for inner function declarations. So move the
original one to more appropriate name, pci_hw.h.
