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: 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.

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

But apparently it was used also for e500v1 platforms mpc8540, mpc8541, mpc8555 and mpc8560. e500v1 cores compared to e500v2 do not support double precision floating point SPE instructions.
