Subject: [PATCH] video: fbdev: controlfb: Fix build for COMPILE_TEST=y && PPC_PMAC=n

The build is currently broken, if COMPILE_TEST=y and PPC_PMAC=n:

  linux/drivers/video/fbdev/controlfb.c: In function ‘control_set_hardware’:
  linux/drivers/video/fbdev/controlfb.c:276:2: error: implicit declaration of function ‘btext_update_display’
    276 |  btext_update_display(p->frame_buffer_phys + CTRLFB_OFF,
        |  ^~~~~~~~~~~~~~~~~~~~

Fix it by including btext.h whenever CONFIG_BOOTX_TEXT is enabled.

Does anyone mind if I apply this via the powerpc tree for v5.9?

It would be nice to get the build clean.

cheers
