Add SP804 delay timer support to the FVP BSP.
This commit simply provides the 3 constants needed by the SP804
delay timer driver and calls sp804_timer_init() in
bl2_platform_setup(). The BSP does not currently use the delay
timer functions.
Note that the FVP SP804 is a normal world accessible peripheral
and should not be used by the secure world after transition
to the normal world.

This patch fixes the incorrect bit width used to extract the wakeup
reason from PSYSR in platform_get_entrypoint() function. This defect
did not have any observed regression.

On ARM standard platforms, snoop and DVM requests used to be enabled
for the primary CPU's cluster only in the first EL3 bootloader.
In other words, if the platform reset into BL1 then CCI coherency
would be enabled by BL1 only, and not by BL3-1 again.
However, this doesn't cater for platforms that use BL3-1 along with
a non-TF ROM bootloader that doesn't enable snoop and DVM requests.
In this case, CCI coherency is never enabled.
This patch modifies the function bl31_early_platform_setup() on
ARM standard platforms so that it always enables snoop and DVM
requests regardless of whether earlier bootloader stages have
already done it. There is no harm in executing this code twice.
ARM Trusted Firmware Design document updated accordingly.

Fix the return type of the FVP `plat_arm_topology_setup` function
to be `void` instead of `int` to match the declaration in
`plat_arm.h`.
This does not result in any change in behavior.

Move the FVP port from plat/fvp to plat/arm/board/fvp. Also rename
some of the files so they are consistently prefixed with fvp_.
Update the platform makefiles accordingly.
