This implements a new and refined UAPI interface that should improve
stability during suspend and move some responsibility into userspace,
making the driver simpler.
It also fixes some sleep issues due to improper shutdown of the device.

For 5.8, we are going to make iptsd the default, which mostly supports
4.19 level multitouch, instead of just singletouch + stylus.
This replaces the old ipts driver with the new UAPI version that is
required for iptsd.

For details, take a look at the commit history of kernel repo linked

Note: currently, this patch is available upstream only on v5.8,
v5.7, and v5.4 and not backported to any older LTS kernels. So,
this patch was backported from upstream commit ourselves.
