Speedup BGX link polling on ARM64

The previous values caused the callout thread stall for 100ms each 2s
if no link is present. Dtrace analysis showed that it has significant
impact on overall interrupt performance.
Decrease these values by a factor of 100.

Fix finding appropriate BGX node in DTB and move it to a separate function

Search for BGX node in DTS in two ways:
1. Try to find it uder root node first
2. If not found under root, find the top level PCI bridge node
and search all nodes below it until appropriate BGX node is found.
Move search code to another function to make the code more clear.
Remove unused variable by the way.

Introduce initial support for Cavium's ThunderX networking interface

- The driver consists of three main componens: PF, VF, BGX
- Requires appropriate entries in DTS and MDIO driver
- Supports only FDT configuration
- Multiple Tx queues and single Rx queue supported
- No RSS, HW checksum and TSO support
- No more than 8 queues per-IF (only one Queue Set per IF)
- HW statistics enabled
- Works in all available MAC modes (1,10,20,40G)
- Style converted to BSD according to style(9)
- The code brings lmac_if interface used by the BGX driver to
update its logical MACs state.
