[PATCH] NAND: fsl_upm: fix build problem with 2.6.28-rc2

[Wolfgang Grandegger <wg@grandegger.com>]

This patch fixes a problem with building the 2.6.28-rc2 kernel with
FSL UPM NAND support for the TQM8548 modules. For some reason
of_mtd_parse_partitions() requires on argument less in the meantime.
Furthermore, the return value is checks properly.
