The new subtree model brings the subtrees up from the openbmc-machines
layer.

This includes the 'pnorboot' tool for configuring the LPC firmware
mapping.
This is used by Palmetto instead of mboxd, as Palmetto only requires the
LPC mapping component. The mbox component causes interrupts to be
continually triggered on the host, causing unnecessary CPU load.
As Palmetto is the only in-tree user of this tool, the service file hard
codes the PNOR size. If we merge machines in the future this should be
configured by the machine layer.
Resolves: openbmc/openbmc#3357
Tested: Booted host on Palmetto, checked interrupt count

When we move to the 4.13 kernel tree, the LPC bus needs to be configured
through the ASPEED_LPC_CTRL_IOCTL_MAP ioctl or else the BMC will not
expose the boot firmware to the host.
We enable it on Palmetto despite P8 host firmware not speaking the mbox
protocol, as mboxd in that case sits there and doesn't do much aside
from configure the LPC firmware mapping to point to flash. In the future
if someone adds support to the host firmware, the BMC will not require
any changes.
Tested: Booted on Palmetto host up to Petitboot
