Rather than create a new armv8 board similar to armltd/vexpress64, add semihosting calls to the existing one, enabled with CONFIG_SEMIHOSTING and CONFIG_BASE_FVP both set. Also reuse the existing board config file -vexpress_aemv8.h but differentiate the two models by the presence or +vexpress_aemv8a.h but differentiate the two models by the presence or absence of CONFIG_BASE_FVP.
