Replace all SCP FW (BL0, BL3-0) references
This patch replaces all references to the SCP Firmware (BL0, BL30, BL3-0, bl30) with the image terminology detailed in the TF wiki (https://github.com/ARM-software/arm-trusted-firmware/wiki):
BL0 --> SCP_BL1 BL30, BL3-0 --> SCP_BL2 bl30 --> scp_bl2
This change affects code, documentation, build system, tools and platform ports that load SCP firmware. ARM plaforms have been updated to the new porting API.
IMPORTANT: build option to specify the SCP FW image has changed:
BL30 --> SCP_BL2
IMPORTANT: This patch breaks compatibility for platforms that use BL2 to load SCP firmware. Affected platforms must be updated as follows:
BL30_IMAGE_ID --> SCP_BL2_IMAGE_ID BL30_BASE --> SCP_BL2_BASE bl2_plat_get_bl30_meminfo() --> bl2_plat_get_scp_bl2_meminfo() bl2_plat_handle_bl30() --> bl2_plat_handle_scp_bl2()

Fix SP804 delay timer on FVP
This patch fixes several issues with the SP804 delay timer on FVP:
* By default, the SP804 dual timer on FVP runs at 32 KHz. In order to run the timer at 35 MHz (as specified in the FVP user manual) the Overwrite bit in the SP810 control register must be set.
* The CLKMULT and CLKDIV definitions are mixed up:
delta(us) = delta(ticks) * T(us) = delta(ticks) / f(MHz)
From the delay function:
delta_us = (delta * ops->clk_mult) / ops->clk_div;
Matching both expressions:
1 / f(MHz) = ops->clk_mult / ops->clk_div
And consequently:
f(MHz) = ops->clk_div / ops->clk_mult
Which, for a 35 MHz timer, translates to:
ops->clk_div = 35 ops->clk_mult = 1
* The comment in the delay timer header file has been corrected: The ratio of the multiplier and the divider is the clock period in microseconds, not the frequency.

TBB: add Trusted Watchdog support on ARM platforms
This patch adds watchdog support on ARM platforms (FVP and Juno). A secure instance of SP805 is used as Trusted Watchdog. It is entirely managed in BL1, being enabled in the early platform setup hook and disabled in the exit hook. By default, the watchdog is enabled in every build (even when TBB is disabled).
A new ARM platform specific build option `ARM_DISABLE_TRUSTED_WDOG` has been introduced to allow the user to disable the watchdog at build time. This feature may be used for testing or debugging purposes.
Specific error handlers for Juno and FVP are also provided in this patch. These handlers will be called after an image load or authentication error. On FVP, the Table of Contents (ToC) in the FIP is erased. On Juno, the corresponding error code is stored in the V2M Non-Volatile flags register. In both cases, the CPU spins until a watchdog reset is generated after 256 seconds (as specified in the TBBR document).
