PATCH 1/1 arm: omap2plus_defconfig: enable SPLIT and DWARF4

CONFIG_DEBUG_INFO_SPLIT will split debug info on .dwo files. This will generate a smaller vmlinux and smaller .ko modules, which will be easier to ship on certain products.

CONFIG_DEBUG_INFO_DWARF4 will generate debug info in DWARF4 format, which ends up being larger, but improves the probability of resolving variables in optmized code.

Nice, this makes my initramfs go down from about 17MB to 4.7 MB :)
