Input: silead - Always support 10 fingers
When support for Silead touchscreens was orginal added some touchscreens
with older firmware versions only supported 5 fingers and this was made
the default requiring the setting of a "silead,max-fingers=10" uint32
device-property for all touchscreen models which do support 10 fingers.
There are very few models with the old 5 finger fw, so in practice the
setting of the "silead,max-fingers=10" is boilerplate which needs to
be copy and pasted to every touchscreen config.
Reporting that 10 fingers are supported on devices which only support
5 fingers doesn't cause any problems for userspace in practice, since
at max 4 finger gestures are supported anyways. Drop the max_fingers
configuration and simply always assume 10 fingers.
