[patch 2/4] Make partitions optional in physmap_of

[Josh Boyer]

The latest physmap_of driver has a small error where it will fail the probe
with:

physmap-flash: probe of fff00000.small-flas failed with error -2

if there are no partition subnodes in the device tree and the old style binding
is not used.  Since partition definitions are optional, the probe should still
succeed.
