initramfs: generalize initramfs_data.xxx.S variants

Remove initramfs_data.{lzo,lzma,gz,bz2}.S variants and use a common
implementation in initramfs_data.S.  The common implementation expects the
file name of the initramfs to be defined in INITRAMFS_IMAGE.

Change the Makefile to set the INITRAMFS_IMAGE define symbol according
to the selected compression method.

-  initramfs_data includes the compressed binary that is the
-  filesystem used for early user space.
-  Note: Older versions of "as" (prior to binutils 2.11.90.0.23
-  released on 2001-07-14) dit not support .incbin.
-  If you are forced to use older binutils than that then the
-  following trick can be applied to create the resulting binary:
-
-
-  ld -m elf_i386  --format binary --oformat elf32-i386 -r \
-  -T initramfs_data.scr initramfs_data.cpio.gz -o initramfs_data.o
-   ld -m elf_i386  -r -o built-in.o initramfs_data.o
-
-  initramfs_data.scr looks like this:
-SECTIONS
-{
-       .init.ramfs : { *(.data) }
-}
-
-  The above example is for i386 - the parameters vary from architectures.
-  Eventually look up LDFLAGS_BLOB in an older version of the
-  arch/$(ARCH)/Makefile to see the flags used before .incbin was introduced.
-
-  Using .incbin has the advantage over ld that the correct flags are set
-  in the ELF header, as required by certain architectures.
