Remove options VESA from x86 GENERIC

options VESA / vesa.ko provides VESA Bios Extensions (VBE) support for
the legacy sc(4) console. It is not used by the default console, vt(4).

There is a report[1] of an incompatibility between VESA and the Nvidia
driver breaking suspend/resume. Since VESA is not used by the default
configuration anyway, just remove options VESA from GENERIC. The kernel
module is still available and may be loaded by sc(4) users who want to
select a VBE mode.

(Note that vt(4) does not support selecting a VBE mode. The loader can
set a VBE mode and vt(4) will use it via the vt_vbefb driver.)
