If the persistent bit is set in a IPMI network override, overwrite any
existing interface config in NVRAM with the new network override.

On BMC platforms the 'Get System Boot Options' command can also be used
to check for a temporary network interface config override. This is
implemented via the optional 'OEM Parameters' field defined in the IPMI
v2 spec. We define the actual format of the field as:
- 4 byte cookie value
- 2 byte version value
- 1 byte hardware address size
- 1 byte IP address size
- Hardware address
- 1 byte flags for 'ignore' and 'method'
And for static configs:
- IP Address
- 1 byte subnet value
- Gateway address
If set the config override replaces any other interface config, forcing
the use of the specified configuration.

On BMC machines the "Get Device ID" and "Get BMC Golden Side Version"
IPMI commands are available. If possible retrieve some interesting
version numbers and display them in the System Information screen.

Move the ipmi_bootdev definition to types.h to support returning
descriptive strings to the system configuration UI.

This is to indicate to a BMC that we have initiated OS boot.
This patch manually parses the device tree for the sensor information.
In the future this could be replaced by libfdt or similar.
Discover the id of your OS Boot sensor:
$ sudo ipmitool sensor get "OS Boot"
Locating sensor record...
Sensor ID : OS Boot (0x5a)
Entity ID : 35.0 (Operating System)
Sensor Type (Discrete): OS Boot (0x1f)
Sensor Reading : 0h
Event Message Control : Per-threshold
Assertion Events : OS Boot
[boot completed - device not specified]
Assertions Enabled : OS Boot
[A: boot completed]
[C: boot completed]
[PXE boot completed]
[Diagnostic boot completed]
[CD-ROM boot completed]
[ROM boot completed]
[boot completed - device not specified]
[Installation started]
[Installation completed]
[Installation aborted]
[Installation failed]
OEM : 0
In this case it is 0x1f. Note that the sesnor is currently asserted iwth boot
completed - device not specified.
Test by clearing all assertions in the OS Boot sensor:
$ sudo ipmitool raw 0x04 0x30 0x5a 0x30 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
$ sudo ipmitool sensor get "OS Boot"
Locating sensor record...
Sensor ID : OS Boot (0x5a)
Entity ID : 35.0 (Operating System)
Sensor Type (Discrete): OS Boot (0x1f)
Sensor Reading : 0h
Event Message Control : Per-threshold
Assertions Enabled : OS Boot
[A: boot completed]
[C: boot completed]
[PXE boot completed]
[Diagnostic boot completed]
[CD-ROM boot completed]
[ROM boot completed]
[boot completed - device not specified]
[Installation started]
[Installation completed]
[Installation aborted]
[Installation failed]
OEM : 0
Then reboot your system. The assertion event should once more say "boot
completed - device not specified".

This change adds a direct IPMI interface to the /dev/ipmi0 device node,
which is present on OpenPower machines.

We'd like to add a new backend to the bootdev storage, so move the
common bootdev-handling code into separate functions, moving
ipmi_bootdev_is_valid to ipmi.c.

Move our IPMI-specific definitions to a separate header, and a
mostly-empty ipmi.c file. We'll populate this with IPMI functionality in
later changes.
