[PATCH] simpldrm: Enable boot time VESA graphic mode selection.
From: Michal Suchanek <hidden>

Since switch to 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.
