Add pixel clock for second LCDIFv3 interface. Both LCDIFv3 interfaces use
the same set of parent clock, so deduplicate imx8mp_media_disp1_pix_sels
into common imx8mp_media_disp_pix_sels and use it for both.

The device number is currently a value that needs to be the same
on two separate tables, but the code doesn't actually enforce it,
leading to errors as boards get added or removed.
Fix it by using an enum.

Reuse the generic swiotlb initialization for xen-swiotlb. For ARM/ARM64
this works trivially, while for x86 xen_swiotlb_fixup needs to be passed
as the remap argument to swiotlb_init_remap/swiotlb_init_late.
Note that the lower bound of the swiotlb size is changed to the smaller
IO_TLB_MIN_SLABS based value with this patch, but that is fine as the
2MB value used in Xen before was just an optimization and is not the
hard lower bound.

Note that this patch removes the possibility to force xen-swiotlb use
