With this kallsyms finally start working at least on ARM. This
enables us resolving addresses into symbols which is particularly
useful in combination with stack unwinding support. As kallsyms
now compile and work we can remove the depends on BROKEN.

this will all to simplify the sync with the kernel and later easly add the
self decompression support to barebox
as example with a lzo compression will reduce barebox from 180224 to 99863
bytes so 55.41%
-rwxr-xr-x 1 root root 99863 Jan 28 02:17 build/versatilepb/barebox.bin.lzo
we also reduce the binary size by 224 bytes

The idea is to panic() when there is no memory available for normal
operation. Exception: code which can consume arbitrary amount of RAM
(example: files allocated in ramfs) must report error instead of panic().
This patch also fixes code which didn't check for NULL from malloc() etc.
Usage: malloc(), memalign() return NULL when out of RAM.
xmalloc(), xmemalign() always return non-NULL or panic().

The do_devinfo_subtree() function is only used if devinfo is compiled
in, so put it under the same ifdef. This avoids the following warning
when built with allnoconfig:
lib/driver.c:247: warning: 'do_devinfo_subtree' defined but not used

dev_name is supposed to return the name of the device plus the id
currently we use %s%d format where in the kernel the use %s.%d
we may think to switch to this format for the device name and keeping the %s%d
for the devfs
this will be usefull to not modify the clock device name as example

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

We accidently have two list implementations in the tree:
include/list.h and include/linux/list.h. This patch moves
the latter (newer one) to include/linux/list.h.

No need to check for maximum argument counts. The commands are
safe to be called with more arguments, so lets safe some bytes.
