Migrate FVP port to use common code

Major update to the FVP platform port to use the common platform code
in (include/)plat/arm/* and (include/)plat/common/*. This mainly
consists of removing duplicated code but also introduces some small
behavioural changes where there was unnecessary variation between the
FVP and Juno ports. See earlier commit titled `Add common ARM and CSS
platform code` for details.

Also add support for Foundation FVP version 9.1 during FVP config
setup to prevent a warning being emitted in the console.
