This patch removes the unused header from the Tegra194
platform files. As a result, the TSA MMIO would be
removed from the memory map too.

The driver initially contained the setup steps to help Tegra186
and Tegra194 SoCs. In order to support future SoCs and make sure
that the driver remains generic enough, some code should be moved
to SoC.
This patch creates a setup handler for a platform to implement its
initialization sequence.

Tegra194: introduce support for `SPD=spmd`
Tegra: introduce backend support to compile libfdt
Tegra: disable signed comparison
plat: common: include "bl_common.h" from plat_spmd_manifest.c
This patch adds a very rudimentary driver for the SPMI arbitrator used
to access the PMIC. It doesn't support all the controller's actual
arbitration features, so it should probably not be used concurrently
with a running kernel (and it's also not optimized for performance). But
it can be used to set a few registers during boot or on shutdown to
control reset handling, which is all we need it for.

Upon booting, the SPMC running on the primary core shall register the
secondary core entry points to which a given secondary core being woken
up shall jump to into the SPMC . The current implementation assumes the
SPMC calls a registering service implemented in the SPMD for each core
identified by its MPIDR. This can typically happen in a simple loop
implemented in the early SPMC initialization routines by passing each
core identifier associated with an entry point address and context
information.
This service is implemented on top of a more generic SPMC<=>SPMD
interface using direct request/response message passing as defined by
the FF-A specification.
