This introduces support for the NC-SI protocol, modelled as a phy driver
for other ethernet drivers to consume.
NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).
This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).
The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
field definitions.

Azure/Travis: Re-sync jobs and clarify exclusions
We keep both of these jobs in sync as much as possible even when the
primary motivation is to keep Travis from exceeding the build time limit
there. With that in mind:
- Use "rk" not "rockchip" to get all Rockchip SoC platforms in one job,
rather than just all Rockchip vendor platforms.
- The NXP LX216* SoCs have their own job, exclude them from the AArch64
generic job.
- SoCFPGA SoCs have their own job, exclude them from the AArch64 generic
job.

serial_lpuart: make clock failure less verbose
Some device may enable CONFIG_CLK but not still support this clock in
CC, so better use debug() in place of dev_warn() otherwise a lot of
boards will throw useless dev_warn()s.

imx8mm/mn: Add missing root clock entry for ARM core clock
The current implementation in arch/arm/mach-imx/cpu.c uses non-DM
code to retrieve the core clock frequency. As the root clock is not
listed we currently get:
CPU: Freescale i.MX8MMQ rev1.0 at 0 MHz
Fix this by adding the missing entry, which results in:

mx6cuboxi: don't disable fdt relocation
fdt_high value of 0xffffffff disables fdt relocation on boot. We don't
need that for Cubox-i/Hummingboard. Rely on generic code to find the
optimal fdt location at boot time.
, which causes the console to not show characters after the LPUART driver
is probed as the 'baudrate' variable is not properly translated.
Fix it by splitting the console variable in two parts: one for the
ttyLP0 part and the other one for the baudrate, which matches the way
it is done on other i.MX targets.
Tested by successfully booting a mainline kernel on a i.MX8QXP MEK
board.
