Subject: [PATCH 0/3] of: Reimplement of_(bus_)?n_(size|addr)_cells()

This series reworks the of_(bus_)?n_(size|addr)_cells() functions. They 
fail to hold the DT spinlock while accessing 'parent' pointer and don't 
hold a reference to the parent node. Neither is likely a real issue as 
most nodes are static.

With these issues fixed, we can then replace the open coded version in 
of_irq_parse_raw().

This series depends on the fixes from this series[1].

      of: Add an iterator to walk up parent nodes
      of: Add missing locking to of_(bus_)?n_(size|addr)_cells()
      of/irq: Use of_bus_n_addr_cells() to retrieve "#address-cells"
