kernel: move linux, part-probe dt parsing in generic code

The "linux,part-probe" dts parsing is a pretty neat generic feature.
It has been posted to kernel.org and could easily be reused by all
targets.

This change moves the patch to the 3.18 and 4.1 generic folders, and
makes the feature available to all platforms who may want to use it.

+Subject: [PATCH 4/8] 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.

++		    which should be used to parse the partition table.
++		    They will be tried in the specified ordering and
++		    the next one will be used if the previous one
++		    failed.
++
++		    Example: linux,part-probe = "cmdlinepart", "ofpart";
++
++		    This is also the default value, which will be used
++		    if this attribute is not specified. It could be
++		    that the flash driver in use overwrote the default
++		    value and uses some other default.
++
++		    Possible values are: bcm47xxpart, afs, ar7part,
++		    ofoldpart, ofpart, bcm63xxpart, RedBoot, cmdlinepart
++
+ The ECC strength and ECC step size properties define the correction capability
+ of a controller. Together, they say a controller can correct "{strength} bit
+ errors per {size} bytes".
