To avoid configuration for both kernel driver
and userspace SDK outside DPDK, we add switch
management in FM10K DPDK PMD driver.

Split dev init to 2 parts.
First only register the port in switch
management; second init hook will be
called after all the pf are registered
and switch initialization. It will finish
dev init. Also add switch interrupt support.
Add fm10k_mirror_rule_set/fm10k_mirror_rule_reset
to support mirror operation. Add fm10k_dev_filter_ctrl
to support flow operation.
Add dpdk port and pf mapping, so
the dpdk port can map to a specific pf
and 1 dpdk port can map to 2 pf to get
total 100G throughput.

Add flow interface to support offload flow into HW.
It supports parse vlan and parse mpls, all these
data will be transffered to ffu data.
Add switch management, includes initialization,
port mapping, epl port link, LED controller, interrupt handler.
It create 3 threads. One for interrupt handler, one for
LED controller, one for statistics.

Add ffu to support offload flow into HW.
It supports forward, mirror, push VLAN, pop VLAN.
It also supports flowset for a group flow definition.
The config file can configure debug log, port speed,
epl port mapping dpdk port, flowset. All these configuration
will be used by switch management.
Statistics includes epl port, ffu rule, dpdk port, and error.
All these statistics data are read from HW.
Modify switch header file to support getting logical port
and glort and device info.

Add epl serdes include loading spico,
controling pcsl, dma, dfe, ical. Add spico code.
Add state machine for epl lane and port, it creates
a pthread to handle the state changing event.
Add external port management, which will use
state machine to handle the event from lane and port.
The lane state will change between DOWN, WAIT_PLL_LOCK,
WAIT_SIGNAL_OK, WAIT_DFE_ICAL, WAIT_DFE_PCAL, UP.
The port state will change between DOWN, WAIT_LANE_UP, UP.

Add I2C to control the inside LED and PHY.
All the operations of I2C are using fm10k I2C register.
Add SBUS to communicate with spico(micro code in serdes)
by using fm10k SBUS register. This is like I2C operations.
Add registers defination, which include all the registers
will be used in the driver. Add switch management log API.
Add switch management structures. Modify Makefile to add
new files building
