This patch overrides the default handlers to get BL31 arguments from the
previous bootloader. The previous bootloader stores the pointer to the
arguments in PMC secure scratch register #53.

BL31 is the first component running on the CPU, as there isn't a previous
bootloader. We set the RESET_TO_BL31 flag to enable the path which assumes
that there are no input parameters passed by the previous bootloader.

Uncore perfmon appears to the CPU as a set of uncore perfmon registers
which can be read and written using the ARI interface. The MCE code
sequence handles reads and writes to these registers by manipulating
the underlying T186 uncore hardware.

To access an uncore perfmon register, CPU software writes the ARI
request registers to specify

* whether the operation is a read or a write,
* which uncore perfmon register to access,
* the uncore perfmon unit, group, and counter number (if necessary),
* the data to write (if the operation is a write).

It then initiates an ARI request to run the uncore perfmon sequence in
the MCE and reads the resulting value of the uncore perfmon register
and any status information from the ARI response registers.

The NS world's MCE driver issues MCE_CMD_UNCORE_PERFMON_REQ command
for the EL3 layer to start the entire sequence. Once the request
completes, the NS world would receive the command status in the X0
register and the command data in the X1 register.

This patch implements the `get_target_pwr_state` handler for Tegra186
SoCs. The SoC port uses this handler to find out the cluster/system
state during CPU_SUSPEND, CPU_OFF and SYSTEM_SUSPEND calls.

The MCE firmware controls the power state of the CPU/CLuster/System,
so we query it to get the state and act accordingly.

This patch adds a helper function to the MCE driver to allow its
clients to issue UPDATE_CSTATE_INFO requests, without having to
setup the CPU context struct.

We introduced a struct to encapsulate the request parameters, that
clients can pass on to the MCE driver. The MCE driver gets the
parameters from the struct and programs the hardware accordingly.

Tegra186 platform support v2

Juno platform Makefile is responsible for enabling all the relevant
errata. As the Juno platform port does not know which revision of Juno
the TF
is compiled for, the revision of the cores are unknown and so all errata
up to this date are needed on at least one revision of Juno.

This patch resets the CPU power state info when we online any CPU. The
NS world software would re-init the CPU power state after the CPU gets
online anyways. This allows us to maintain proper CPU/cluster power
states in the MCE firmware at all times.

At present, the build option checks are done prior to inclusion of
BL makefiles. This meant if the BL makefiles modified any of the options
then these checks were bypassed. This patch corrects this problem.

This patch re-factors the following headers to make it easier to
integrate the PSCI library with an AArch32 Secure Payload :

  *  bl_common.h : The entry point information and the param
     header data structures are factored out into separate
     headers ep_info.h and param_headers.h
  *  psci.h : The PSCI library interfaces are factored out
     into the new header psci_lib.h
  *  context_mgmt.h : The header file is modified to not include
     arch.h when compiled for AArch32 mode.

No functional changes are introduced by this patch.

This patch modifies some of the functions in ARM platform layer to cater
for the case when multi-threading `MT` is set in MPIDR. A new build flag
`ARM_PLAT_MT` is added, and when enabled, the functions accessing MPIDR
now assume that the `MT` bit is set for the platform and access the bit
fields accordingly.

Also, a new API plat_arm_get_cpu_pe_count is added when `ARM_PLAT_MT` is
enabled, returning the PE count within the physical cpu corresponding to
`mpidr`.
