Fix various kernel-doc warnings in lib/ due to missing or erroneous
function names.

Add kernel-doc for some function parameters that was missing.  Use
kernel-doc "Return:" notation in earlycpio.c.

Quietens the following warnings:

  lib/earlycpio.c:61: warning: expecting prototype for cpio_data find_cpio_data(). Prototype was for find_cpio_data() instead

  lib/lru_cache.c:640: warning: expecting prototype for lc_dump(). Prototype was for lc_seq_dump_details() instead
  lru_cache.c:90: warning: Function parameter or member 'cache' not described in 'lc_create'

  lib/parman.c:368: warning: expecting prototype for parman_item_del(). Prototype was for parman_item_remove() instead
  parman.c:309: warning: Excess function parameter 'prority' description in 'parman_prio_init'

  lib/radix-tree.c:703: warning: expecting prototype for __radix_tree_insert(). Prototype was for radix_tree_insert() instead
  radix-tree.c:180: warning: Excess function parameter 'addr' description in 'radix_tree_find_next_bit'
  radix-tree.c:180: warning: Excess function parameter 'size' description in 'radix_tree_find_next_bit'

The comments of find_cpio_data() says:

  * @offset: When a matching file is found, this is the offset to the
  *          beginning of the cpio. ......

But according to the code,

  dptr = PTR_ALIGN(p + ch[C_NAMESIZE], 4);
  nptr = PTR_ALIGN(dptr + ch[C_FILESIZE], 4);
  ....
  *offset = (long)nptr - (long)data;	/* data is the cpio file */

@offset is the offset of the next file, not the matching file itself.
This is confused and may cause unnecessary waste of time to debug.
So fix it.

As Tejun Heo suggested, rename @offset to @nextoff which is more clear
to users. And also adjust the new comments.

The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

This removes all the uses of the __cpuinit macros from C files in
the core kernel directories (kernel, init, lib, mm, and include)
that don't really have a specific maintainer.

Add a simple cpio decoder without library dependencies for the purpose
of extracting components from the initramfs blob for early kernel
uses.  Intended consumers so far are microcode and ACPI override.
