Hi All,

The latest mainline kernel branch fails to build xtensa, mips, arm allmodconfig
with the error:

drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c: In function 'mxc_isi_channel_set_inbuf':
drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c:33:5: error: "CONFIG_ARCH_DMA_ADDR_T_64BIT" is not defined, evaluates to 0 [-Werror=undef]
   33 | #if CONFIG_ARCH_DMA_ADDR_T_64BIT
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

git bisect pointed to cf21f328fcaf ("media: nxp: Add i.MX8 ISI driver")

I will be happy to test any patch or provide any extra log if needed.
