gpu: nvgpu: Fixups for tmake build

Mostly just including necessary includes to make sure that
global function declarations actually match their implementations.

Also work around pointer munging warning:

/build/ddpx/linux/kernel/nvgpu/drivers/gpu/nvgpu/common/pmu/pmu.c: In function 'nvgpu_pmu_process_init_msg':
/build/ddpx/linux/kernel/nvgpu/drivers/gpu/nvgpu/common/pmu/pmu.c:348:4: error: dereferencing type-punned pointer will break strict-aliasing rules [-Werror=strict-aliasing]
    (*(u32 *)gid_data.signature == PMU_SHA1_GID_SIGNATURE);

Work around this warning by simply moving the type punning.
This code is certainly dangerous - it assumes the endianness
of the header data is the same as the machine this code is
running on. Apparently it works, though, so this ignores
the warning.
