RISC-V: defconfigs: Set CONFIG_FB=y, for FB console

[ Upstream commit 3d12b634fe8206ea974c6061a3f3eea529ffbc48 ]

We have CONFIG_FRAMEBUFFER_CONSOLE=y in the defconfigs, but that depends
on CONFIG_FB so it's not actually getting set.  I'm assuming most users
on real systems want a framebuffer console, so this enables CONFIG_FB to
allow that to take effect.
