gpu: nvgpu: update the config options & makefile

Browse Source 
Added dependency between the Kconfig options as follows where
'->' indicates 'depends on' relation:

SUPPORT_CDE -> COMPRESSION -> DMABUF_HAS_DRVDATA
DGPU -> GK20A_PCI

Defined Kconfig option for VPR and for DGPU that is dependent GK20A_PCI
as well. DGPU related sources are now compiled under config flag DGPU.
Also update conditional compilation of the driver paths w.r.t DGPU,
VPR and COMPRESSION flags.
