Since switch to simplefb/simpledrm VESA graphic modes are no longer available with legacy BIOS. The x86 realmode boot code enables the VESA graphic modes when option FB_BOOT_VESA_SUPPORT is enabled. To enable use of VESA modes with simpledrm in legacy BIOS boot mode drop dependency of BOOT_VESA_SUPPORT on FB, also drop the FB_ prefix, and select the option when simpledrm is built-in on x86.

This isn't an fb option any longer. Should we move this into arch/x86/Kconfig ?
