arm64: versal: Drop static DDR and PCIe MMU mappings
AM011 Versal ACAP TRM, Table 43, defines:
- 0x006_0000_0000 - 0x007_FFFF_FFFF PCIe region 1
- 0x008_0000_0000 - 0x00F_FFFF_FFFF DDR controller 0 region 1
- 0x040_0000_0000 - 0x04F_FFFF_FFFF HBM0
- 0x050_0000_0000 - 0x05F_FFFF_FFFF HBM1
- 0x060_0000_0000 - 0x06F_FFFF_FFFF HBM2
- 0x070_0000_0000 - 0x07F_FFFF_FFFF HBM3
- 0x080_0000_0000 - 0x0BF_FFFF_FFFF PCIe region 2
- 0x0C0_0000_0000 - 0x0FF_FFFF_FFFF DDR controller 0 region 2
The old static normal-memory mapping spans PCIe, while DDR coverage is
already populated later from the DRAM banks discovered by mem_map_fill().
Drop the stale static mapping so the MMU table matches the Versal address
map. Also matting was using wrong attributes.
