vexpress64: get rid of CONFIG_SYS_EXTRA_OPTIONS
The Versatile Express ARMv8 semihosted FVP platform is still using the legacy CONFIG_SYS_EXTRA_OPTIONS method to configure some compile-time flags. Get rid of this and create a Kconfig entry for the FVP model, and a selectable bool for the semihosting library. The FVP subboard is now modeled as a target choice so we can eventually choose between different ARMv8 versatile express boards (FVP, base model, Juno...) this way. All dependent symbols are updated to reflect this. The 64bit Versatile Express board symbols are renamed VEXPRESS64 so we have some chance to see what is actually going on. Tested on the FVP fast model. Acked-by: Steve Rae <srae@broadcom.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
