ARM: dts: msm: adjust display y-coord and add firmware image name

Input framework scales the raw touch data to adapt the LCD
display if the raw data value exceeds the display max width or
height. For Synaptics S3027A controller on 8916 QRD, maximum Y
resolution is 1900 pixels and maximum display coordinate is 1756
pixels. Update these values in the DT node of Synaptics along with
adding the firmware image name.
