adm5120: Remove unmaintained target

This target only supports kernel 3.18, which is not supported in OpenWrt
any more for multiple releases. It also looks like there is no active
maintainer for this target.
Remove the code and all the packages which are only used by this target.

To add this target to OpenWrt again port it to a recent and supported
kernel version.

- *
- *
- * 12-Mar-2005  Mineharu Takahara <mtakahar@yahoo.com>
- *   pass actual output size to decoder (stream mode
- *   compressed input is not a requirement anymore)
- *
- * 24-Apr-2005 Oleg I. Vdovikin
- *   reordered functions using lds script, removed forward decl
- *
- * 24-Mar-2007 Gabor Juhos
- *   pass original values of the a0,a1,a2,a3 registers to the kernel
- *
- * 19-May-2007 Gabor Juhos
- *   endiannes related cleanups
- *   add support for decompressing an embedded kernel
