Subject: drm/tegra: Fix cast to restricted __le32
Git-commit: 16693c1b2d98cebc8dedf03b49d1053cf1826c86
Patch-mainline: v5.17-rc6
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Sparse warns about the following cast in the function
falcon_copy_firmware_image() ...

 drivers/gpu/drm/tegra/falcon.c:66:27: warning: cast to restricted __le32

Fix this by casting the firmware data array to __le32 instead of u32.
