This is a longstanding bug, almost unnoticeable when calling
persistent_ram_write() for small buffers.
But when called for large data buffers, the write routine behaves
incorrectly, as the size may never update: instead of clamping
the size to the maximum buffer size, buffer_size_add_clamp() returns
an error (which is never checked by the write routine, btw).
To fix this, we now use buffer_size_add() that actually clamps the
size to the max value.
Also remove buffer_size_add_clamp(), it is no longer needed.

This changes the log initialization to be dynamic, but still
at boot time. These changes are a predecessor to implementing
runtime allocation and freeing of logs, to make the Android logger
less hard-coded.
Change from a fixed set of static log structures, to allocation
at init time into a list. Return proper error numbers on log
allocation failure.

and yet we can throw them all in the trash can and the thing
still builds on x86-64 and ppc, just by deleting the references

If ipack_device_register() returns an error, then we returned a freed
pointer. The caller doesn't use it, but it means we return success to
the user instead of returning an error code.
I kind of rewrote the error handling in this function as a cleanup.
