[ Upstream commit 07e6a553c2f1d385edfc9185081dee442a9dd38d ]

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@fa600000: node has a unit name, but no reg or ranges property
  Warning (simple_bus_reg): /soc/camera@fa600000: missing or empty reg/ranges property

Subtract 0xfa600000 from all its children nodes.  No functional impact
expected.
