[ Upstream commit e7c4ebe2f9cd68588eb24ba4ed122e696e2d5272 ]
Use the general touchscreen method to config the max pressure for touch tsc2046(data sheet suggest 8 bit pressure), otherwise, for ABS_PRESSURE, when config the same max and min value, weston will meet the following issue,
[17:19:39.183] event1 - ADS7846 Touchscreen: is tagged by udev as: Touchscreen [17:19:39.183] event1 - ADS7846 Touchscreen: kernel bug: device has min == max on ABS_PRESSURE [17:19:39.183] event1 - ADS7846 Touchscreen: was rejected [17:19:39.183] event1 - not using input device '/dev/input/event1'
This will then cause the APP weston-touch-calibrator can't list touch devices.
root@imx6ul7d:~# weston-touch-calibrator could not load cursor 'dnd-move' could not load cursor 'dnd-copy' could not load cursor 'dnd-none' No devices listed.
And accroding to binding Doc, "ti,x-max", "ti,y-max", "ti,pressure-max" belong to the deprecated properties, so remove them. Also for "ti,x-min", "ti,y-min", "ti,x-plate-ohms", the value set in dts equal to the default value in driver, so are redundant, also remove here.

Hi!
Did someone check the source code in 4.9? AFAICT it still tries to use the properties, and probing seems to be different from newer kernels.
