Add support for Multi-Physical Function Switch, MPFS, in mlx5en.

MPFS is a logical switch in the Mellanox device which forward packets
based on a hardware driven L2 address table, to one or more physical-
or virtual- functions. The physical- or virtual- function is required
to tell the MPFS by using the MPFS firmware commands, which unicast
MAC addresses it is requesting from the physical port's traffic.
Broadcast and multicast traffic however, is copied to all listening
physical- and virtual- functions and does not need a rule in the MPFS
switching table.

Fix race between driver unload and dumping firmware in mlx5core.

Present code uses lock-less accesses to the dump data to prevent top
level ioctls from blocking bottom-level call to dump. Unfortunately, this
depends on the type stability of the dump data structure, which makes it
non-functional during driver teardown.

Switch to the mutex locking scheme where top levels use the mutex in the
bound regions, while copyouts and drain for completion utilize condvars.
The mutex lifetime is guaranteed to be strictly larger than the time
interval where driver can initiate dump, and most of the control fields
of the old struct mlx5_dump_data are directly embedded into struct
mlx5_core_dev.

Implement a watchdog as part of the healtcare subsystem which
reads the PCI power status during startup and upon the PCI
power status change event and store it into the core device
structure. This value is then exported to user-space via a
read-only SYSCTL. A dmesg print has been added to inform
the admin about the PCI power status.

Correctly define the interface state bits in mlx5en(4).

While at it remove unused interface state bits. This also fixes and issue
during shutdown:

There is an issue where the firmware fails during mlx5_load_one,
the health_care timer detects the issue and schedules a health_care call.
Then the mlx5_load_one detects the issue, cleans up and quits. Then
the health_care starts and calls mlx5_unload_one to clean up the resources
that no longer exist and causes kernel panic.

The root cause is that the bit MLX5_INTERFACE_STATE_DOWN is not set
after mlx5_load_one fails. The solution is removing the bit
MLX5_INTERFACE_STATE_DOWN and quit mlx5_unload_one if the
bit MLX5_INTERFACE_STATE_UP is not set. The bit MLX5_INTERFACE_STATE_DOWN
is redundant and we can use MLX5_INTERFACE_STATE_UP instead.
