media: atomisp: Drop VIDEO_ATOMISP_ISP2401 Kconfig option

Drop the VIDEO_ATOMISP_ISP2401 Kconfig option and the -DISP2401
cflags.

This is no longer necessary since all ISP2400 vs ISP2401 differences
are now dealt with at runtime.

Many thanks to Kate Hsuan for all her work on this.

 2. Items which SHOULD also be fixed eventually:
 
-* Remove VIDEO_ATOMISP_ISP2401, making the driver to auto-detect the
-  register address differences between ISP2400 and ISP2401
-
 * The driver is intended to drive the PCI exposed versions of the device.
   It will not detect those devices enumerated via ACPI as a field of the
   i915 GPU driver (only a problem on BYT).
