kernel: Remove deprecated generic linux,part-probe patch

Browse Source 
This is now replaced by some other mtd partition parsing which was
merged into upstream.

From: Hauke Mehrtens <hauke@hauke-m.de>
Subject: mtd: part: add generic parsing of linux,part-probe
This moves the linux,part-probe device tree parsing code from
physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
providing a reference to their device tree node in struct
mtd_part_parser_data.
THIS METHOD HAS BEEN DEPRECATED
Linux supports "compatible" property in the "partitions" subnode now. It
should be used to specify partitions format (and trigger proper parser
usage) if needed.
