plat/arm/fvp: Support performing SDEI platform setup in runtime

Browse source 
This patch introduces dynamic configuration for SDEI setup and is supported
when the new build flag SDEI_IN_FCONF is enabled. Instead of using C arrays
and processing the configuration at compile time, the config is moved to
dts files. It will be retrieved at runtime during SDEI init, using the fconf
layer.

This is currently an experimental feature.
- ``SDEI_IN_FCONF``: This flag determines whether to configure SDEI setup in
runtime using firmware configuration framework. The platform specific SDEI
shared and private events configuration is retrieved from device tree rather
than static C structures at compile time. This is currently an experimental
feature and is only supported if SDEI_SUPPORT build flag is enabled.
- ``USE_ROMLIB``: This flag determines whether library at ROM will be used.
This feature creates a library of functions to be placed in ROM and thus
