In Linux v6.11, the 'platform_driver' structure 'remove' callback was
updated to return void instead of 'int'. Update the MODS drivers as
necessary to fix this. Note that we can simply remove the mods_dmabuf
'remove' function because it does nothing.

For Linux v6.8, commit ef175b29a242 ("of: Stop circularly including
of_device.h and of_platform.h") updated the OF headers included by these
header files. This breaks the build for various drivers and so fix this
by including the headers that are actually needed for each driver.

Bug 200582229
This change will add smmu mapping/unmapping support for MODS
allocated memory buffer by using kernel smmu api dma_map_sg_attrs()
and dma_unmap_sg_attrs()
1. new IOCTL MODS_ESC_IOMMU_DMA_MAP_MEMORY and
MODS_ESC_IOMMU_DMA_UNMAP_MEMORY is added to do smmu mapping/unmapping
and get smmu mapped address for MODS allocated buffers;
2. a platform device and driver is added to match mods smmu sid in dtb,
the device is used to do smmu mapping/unampping; and mods smmu devices
are added in dtb to match with the driver with smmu config
