[oe] RFC: remove old kernels

[Marcin Juszkiewicz]

Hi

recipes/linux/ contains 235 recipes. I would like to propose cleaning:

1. drop 2.4 kernels - if someone still needs them then .oz354x and .stable
   branches have them.

This may affect:

- zauruses (which have 2.6 kernel)
- ipaq h36/38/39/54/55 - some have 2.6 kernel
- ipod - but does someone really uses 2.4.24 on own ipod?
- ramses - but this is maintained out of tree
- wrt54 - OpenWRT distro works better there and lets keep that way
- xxs1500, mtx, sun4cdm - if someone maintain it at all then please raise your
  hand
- colinux - no one will cry
- geodegx - 2.6 mainline works on it


2. Drop kernels older then 2.6.20 - it was over 3 years ago so if someone uses 
   older one then probably also uses 3 years old OE. 

This may affect (checked recipes):

- ep93xx - machines with this cpu are mainline supported, patches from ts72xx
  and sim.one works
- chumby
- compulab-pxa270
- devkitidp-pxa255
- fsg3
- gumstix
- amsdelta
- bd-neon
- colinux
- epia
- geodelx
- h1940
- h6300
- ks8695
- magicbox
- mtx-3
- neuros
- sun4cdm
- tornado-omap2
- wrap-geode
- x86
- acern30
- logicpd-pxa270
- mainstone
- mx21ads
- netbook-pro
- triton
- blueangel
- universal

Some of those machines are not maintained anymore, many of them should work 
with current mainline kernels. If someone cares about anything on a list - 
raise your hand.

Why 2.6.20? Because NHK-15 uses it and does not work with mainline kernel.
