cgtqmx6-rev.E: update toplevel readme for hardware Rev. E.x boards

Gitlab does not render a markdown README file if it is added as a symbolic
link to a file in eg. the board folder. So the README.md on u-boot root
folder needs to be updated manually.

 These timings node have to be adjusted to use other LVDS displays as the default one which is 1024x768 (18-Bits).
 For this, there are some example device trees available with different LVDS/HDMI outputs:
 
-- `imx6dl-cgtqmx6-hdmi.dts`, `imx6q-cgtqmx6-hdmi.dts`: Only HDMI is enabled, all other LDB-devices/framebuffers are disabled

+As an additional example DT there is `imx6q-cgtqmx6-pwm.dts` which uses HDMI as output and enables all 4 channels of PWM outputs.
