soc: qcom: hgsl: Add doorbell support to gvm 



Used under guest system, it submits GPU tasks into hardware while host
driver is unaware of it.

Hgsl communicates with GPU hardware using either GPU registers or
TCSR compute signaling hardware block.

config QCOM_HGSL

	bool "Graphics driver for Hypervisor"

	depends on QTI_QUIN_GVM

	help

	  This driver could help commands submmitting functions for

	  hypervisor Linux. With HFI feature provided by A6x, it

	  could submit commands directly to hardware without passing

	  them to host system.

	help

	  The TCSR compute signal module provides hgsl driver

	  in hypervisor Linux a way to send/receive signals

	  to/from A6x GPU hardware directly, without going

	  through host system.
