Subject: [PATCH] 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:266:2: error: unknown type name 'uint64_t'
  uint64_t tba_addr;  /* to KFD */
/usr/include/linux/kfd_ioctl.h:267:2: error: unknown type name 'uint64_t'
  uint64_t tma_addr;  /* to KFD */
/usr/include/linux/kfd_ioctl.h:268:2: error: unknown type name 'uint32_t'
  uint32_t gpu_id;  /* to KFD */
/usr/include/linux/kfd_ioctl.h:269:2: error: unknown type name 'uint32_t'
  uint32_t pad;

Fixes: d7b9bd2248d79 ("drm/amdkfd: Add support for user-mode trap handlers")
