[PATCH] of/address: Don't throw errors on absent ranges properties

[Benjamin Herrenschmidt]

The core always tries to translate any "reg" property to construct the platform
device names. This results in a pile of "OF: no ranges; cannot translate" errors
in dmesg whenever we expose things like i2c devices that cannot directly translate
to the MMIO space.

Turn this into a pr_debug instead
