[PATCH] Revert "fbdev: vesafb: Allow to be built if COMPILE_TEST is enabled"

[Javier Martinez Canillas]

This reverts commit fa0e256450f27a7d85f65c63f05e6897954a1d53. The kernel
test robot reported that attempting to build the vesafb driver fails on
some architectures, because these don't define a `struct screen_info`.

This leads to linking errors, for example on parisc with allyesconfig:

  hppa-linux-ld: drivers/video/fbdev/vesafb.o: in function `vesafb_probe':
>> (.text+0x738): undefined reference to `screen_info'
>> hppa-linux-ld: (.text+0x73c): undefined reference to `screen_info'
   hppa-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init':
>> (.init.text+0x28): undefined reference to `screen_info'
>> hppa-linux-ld: (.init.text+0x30): undefined reference to `screen_info'
   hppa-linux-ld: (.init.text+0x78): undefined reference to `screen_info'

The goal of commit fa0e256450f2 ("fbdev: vesafb: Allow to be built if
COMPILE_TEST is enabled") was to have more build coverage for the driver
but it wrongly assumed that all architectures would define a screen_info.
