kernel: mtdsplit_uimage: replace "openwrt, okli" parser



The only difference between the "openwrt,okli" and the generic
parser is the magic.  Set this in device tree for all affected
devices and  remove the "openwrt,okli" parser.

Tested-by: Michael Pratt <mcpratt@protonmail.com> # EAP300 v2, ENS202EXT and ENH202
