drm/amdgpu: fix 32-bit build warning
Casting a pointer to a 64-bit type causes a warning on 32-bit targets:
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gfx_v9.c:473:24: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
lower_32_bits((uint64_t)wptr));
^
drivers/gpu/drm/amd/amdgpu/amdgpu.h:1701:53: note: in definition of macro 'WREG32'
#define WREG32(reg, v) amdgpu_mm_wreg(adev, (reg), (v), 0)
^
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gfx_v9.c:473:10: note: in expansion of macro 'lower_32_bits'
lower_32_bits((uint64_t)wptr));
^~~~~~~~~~~~~
The correct method is to cast to 'uintptr_t'.
