[PATCH 1/1] staging: media: atomisp: Update TODO file

[Sakari Ailus <sakari.ailus@linux.intel.com>]

Update the TODO file to match the current state of affairs. Add sensor
drivers and make adding ISP parameter support optional.

-* Without a 3A library the capture behaviour is not very good. To take a good

-  This MUST be done before moving the driver out of staging so that we can

 2. Items which SHOULD also be fixed eventually:

 * 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).
