Subject: [PATCH v2 3/3] ARM: dts: samsung: s5pv210: fix camera unit addresses/ranges

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@...00000: node has a unit name, but no reg or ranges property
  Warning (simple_bus_reg): /soc/camera@...00000: missing or empty reg/ranges property

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

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
