The struct rte_memzone field .phys_addr is renamed to .iova.
The deprecated name is kept in an anonymous union to avoid breaking
the API.

The function rte_mem_virt2phy() is kept and used in functions which
works only with physical addresses.
For all other calls this function is replaced by rte_mem_virt2iova()
which does a direct mapping (no conversion) in the VA case.
Note: the new function rte_mem_virt2iova() function matches the
behaviour implemented in rte_mem_virt2phy() by the commit
680f6c1260 ("mem: honor IOVA mode in virt2phy")

rte_malloc_virt2phy() does not return a physical address if huge pages
aren't in use. Further, rte_memzone->phys_addr is not a physical address.
Use rte_mem_virt2phy() and manually lock pages to support lack of
huge pages.
Also check the return value of rte_mem_virt2phy()
Verify the function returns an address. Otherwise return an error and
log a message.

1) Move the function reset to bnxt_dev_init.
On the same lines, setup, enable and request interrupt to init path.
Memory allocation is also being done in the init path.
2) After a function reset, configure the VFs. Distribute resources
evenly between all functions (PF and VF) for now. In the future, this
should be controllable.
3) The bnxt_vf_info and bnxt_pf_info had lot of duplication. Move the
common items to struct bnxt. And only unique items specific to PF
remain in the struct bnxt_pf_info.
4) Program the firmware to allow certain commands sent by a VF.
Disallowing these will prevent clean VF driver cleanup.
5) Since PF/VF need to allocate resources from a pool in the hardware,
use func_qcaps and func_qcfg to appropriately query the capabilities
and available resources.
6) If a PF is being initialized and no VFs are allocated, explicitly
call func_cfg to allocate the resources.
7) Once resources are requested from the firmware, update local copy
of resource count in struct bnxt only after sending the func_qcfg to
make sure the allocation request in the firmware went through.
The changes in this patch will be used by the subsequent patches
to allow proper initialization of PF/VF instance.

Otherwise, the inherent cast when multiplying entry_length by max_vnics
in the call to rte_memzone_reserve could promote max_vnics to a signed
value, causing hilarity to ensue...

Add functions to allocate, initialize, and free vnics.
A VNIC represents a virtual interface. It is a resource in the RX path
of the chip and is used to setup various target actions such as RSS,
MAC filtering etc. for the physical function in use.
