[ Upstream commit ba2a45a48503665f7e8eeec51f8b40456566b0cd ]

The camera node has both unit address and children within the same bus
mapping, thus needs proper ranges property to fix dtc W=1 warnings:

  Warning (unit_address_vs_reg): /soc/camera@11800000: node has a unit name, but no reg or ranges property
  Warning (simple_bus_reg): /soc/camera@11800000: missing or empty reg/ranges property

Subtract 0x11800000 from all its children nodes.  No functional impact
expected.
