msm: kgsl: Add Qualcomm GPU driver 



Snapshot of the Qualcomm Adreno GPU driver (KGSL) as of msm-4.9
commit e023d014d2039d59d0999e73984ccf0cc6e60bc7 (msm: pcie:
fix PCIe L0s and L1 ASPM support).

Fixed compile errors,checkpatch issues and API changes:
	*  Rename function _copy_from_user() to kgsl_copy_from_user()
	*  Fixup vm_fault API
	*  Rename fence API to dma_fence API
	*  Stop using scm_call()
	*  Fixup header includes
	*  Fix IDR API usage
	*  Fix __mutex_owner usage

Adreno bus monitor device



kgsl-busmon is a psedo device that represents a devfreq bus bandwidth

governor. If this device is present then two different governors are used

for  GPU DCVS and bus DCVS.



Required properties:

- compatible:	Must be "qcom,kgsl-busmon"

- label:	Device name used for sysfs entry.



Example:



	qcom,kgsl-busmon {

		compatible = "qcom,kgsl-busmon";

		label = "kgsl-busmon";

	};
