bcm53xx: fix NAND partitions on D-Link DIR-885L

This fixes missing rootfs on above device:
[    2.652292] VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6
(...)
[    2.687909] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Fixes: 05cb6aa69f66 ("bcm53xx: replace linux,part-probe with a proper partitions subnode")
