Subject: gpu: nvgpu: Fix missing #includes and fw decls in Linux code

ioctl_channel.h and cde.h referred to multiple structures that were
not forward declared or explitly #included in. Add several forward
declarations and #includes. Also add #include for
<uapi/linux/nvgpu.h> to multiple Linux .c files that were missing it.
