This reverts commit 413821b7 because it
was never reviewed, was buggy (report from kernel test robot:
https://lore.kernel.org/all/202204090333.QZXMI2tu-lkp@intel.com/) and
used undocumented, broken bindings.  Half of the properties in this
device are questioned, thus adding DTS node causes only errors and does
not make the device usable without the bindings and driver part:

  sm7225-fairphone-fp4.dtb: haptics@5a: failed to match any schema with compatible: ['awinic,aw8695']
  sm7225-fairphone-fp4.dtb: haptics@5a: awinic,tset: b'\x12' is not of type 'object', 'array', 'boolean', 'null'
  sm7225-fairphone-fp4.dtb: haptics@5a: awinic,r-spare: b'h' is not of type 'object', 'array', 'boolean', 'null'

Since bindings were abandoned (4 months since review), revert the commit
to avoid false sense of supporting something which is not supported.
