input: touchscreen: st: add trusted touch support 



Add Trusted touch support to lahaina MTP
Touchscreen driver. This feature enables driver to
operate in trusted touch mode in trusted virtual machine(TVM).
The primary virtual machine(PVM) lends resources such
as IO memory and touch irq to TVM prior to trusted touch
is initiated and reclaims those resources back after trusted
touch usecase finishes.The resource requirements of TVM
such as clock, regulators etc are taken care by PVM.
