Michael Ellerman ee68554d2c powerpc/prom_init: Fixup missing powermac #size-cells 
[ Upstream commit cf89c9434a ]

On some powermacs `escc` nodes are missing `#size-cells` properties,
which is deprecated and now triggers a warning at boot since commit
045b14ca5c ("of: WARN on deprecated #address-cells/#size-cells
handling").

For example:

  Missing '#size-cells' in /pci@f2000000/mac-io@c/escc@13000
  WARNING: CPU: 0 PID: 0 at drivers/of/base.c:133 of_bus_n_size_cells+0x98/0x108
  Hardware name: PowerMac3,1 7400 0xc0209 PowerMac
  ...
  Call Trace:
    of_bus_n_size_cells+0x98/0x108 (unreliable)
    of_bus_default_count_cells+0x40/0x60
    __of_get_address+0xc8/0x21c
    __of_address_to_resource+0x5c/0x228
    pmz_init_port+0x5c/0x2ec
    pmz_probe.isra.0+0x144/0x1e4
    pmz_console_init+0x10/0x48
    console_init+0xcc/0x138
    start_kernel+0x5c4/0x694

As powermacs boot via prom_init it's possible to add the missing
properties to the device tree during boot, avoiding the warning. Note
that `escc-legacy` nodes are also missing `#size-cells` properties, but
they are skipped by the macio driver, so leave them alone.
