meta-ibm: Add phal support for p10bmc

OpenBMC requires  additional capabilities for the
OpenPOWER systems such as
 - A common mechanism to access and control the host
   hardware from the BMC.
 - A storage mechanism to store the data that can be
   used for initialize, control and access the CEC
   hardware.
 - An infrastructure to initialize the hardware using
   the hardware procedures provided by the hardware team.
 - Common mechanism to handle the hardware failures for
   the host hardware.

These above features are essential for the BMC to provide
better RAS capability and to support lab debug for the
enterprise class systems.

The phal(POWER Hardware Abstraction Layer) aims to provide
a common layout such that the OpenPOWER  application can
use this infrastructure to boot, enable RAS features like dump,
diagnostics, and lab debug tooling purpose.

The phal is a combination of open source packages that are
tailored/customised  to use in OpenBMC. For instance POWER
hardware access and control is managed through pdbg and
host hardware data modelling is done via devicetree.

phal is group of libraries running in BMC. These libraries
are used by OpenPOWER specific application for host hardware
interactions, Hostboot and SBE initialization, diagnostics
and debugging.
