uapi: fix linux/kfd_ioctl.h userspace compilation errors

Consistently use types provided by <linux/types.h> via <drm/drm.h>
to fix the following linux/kfd_ioctl.h userspace compilation errors:

/usr/include/linux/kfd_ioctl.h:236:2: error: unknown type name 'uint64_t'
  uint64_t va_addr; /* to KFD */
/usr/include/linux/kfd_ioctl.h:237:2: error: unknown type name 'uint32_t'
  uint32_t gpu_id; /* to KFD */
