The codebase was using non-standard headers. It is needed to replace
them by the correct ones so that we can use the new libc headers.

OP-TEE loading is optional on Developerbox controlled via SCP
firmware. To check if OP-TEE is loaded or not, we use DRAM1 region
info passed by SCP firmware.

Add Makefile and plaform definations file.
My thanks to Daniel Thompson and Ard Biesheuvel for the bits and pieces
I've taken from their earlier work regarding build and deploy steps for
Developerbox based on Synquacer SoCs. They deserve much of the credit
for this work although, since I assembled and tested things, any blame
is probably mine.

PSCI framework uses SCPI driver to communicate to SCP firmware for
various power management operations. Following PSCI operations are
supported:
- CPU ON
- CPU OFF
- CPU STANDBY
- SYSTEM RESET
- SYSTEM OFF

Retrieve DRAM info from SCP firmware using SCPI driver. Board supports
multiple DRAM slots so its required to fetch DRAM info from SCP firmware
and pass this info to UEFI via non-secure SRAM.

Add System Control and Power Interface (SCPI) driver which provides APIs
for PSCI framework to work. SCPI driver uses MHU driver APIs to communicate
with SCP firmware for various system control and power operations.

BL31 runs from SRAM which is a non-coherent memory on synquacer. So
enable MMU with SRAM memory marked as Non-Cacheable and mark page tables
kept on SRAM as Non-Cacheable via XLAT_TABLE_NC flag. Also add page tables
for Device address space.

As this platform supports direct entry to BL31 and no BL2, so
populate BL32 and BL33 entrypoints with static memory load info.

synquacer supports direct entry to BL31 without BL1 and BL2 as
SCP firmware does similar work. So this patch adds BL31 stub APIs.
