arm: move CONFIG_TFABOOT to generic Kconfig

Currently, CONFIG_TFABOOT is located in armv8/fsl-layerscape Kconfig,
but it will be also useful for other targets if some additional
configuration are necessary.
So move it to arch/arm/Kconfig.

Please note that CONFIG_TFABOOT still depends on
CONFIG_ARCH_SUPPORT_TFABOOT and so the menu won't come up
if any target doesn't need its own customization for TF-A boot.
This will maintain the compatibility.
