package/devmem2: remove package

Browse Source 
It was here just for backwards compatibility and is not used by any
package or board after commits

  59856480b6 packages/devmem2: remove from all board configurations
  2f6e3eae55 package/ti-gfx: do not use devmem2 in script

There are address casting issues with 32bit access on a 64bit bus (like
on the SoC FPGA ARM processors) with this tool. The Busybox version of
devmem is the most up to date and supports quadword access.

From 6570e7afe1eebd64022b871b9ebd9a76be267f57 Mon Sep 17 00:00:00 2001
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Date: Sun, 29 Jun 2014 16:27:49 +0200
Subject: [PATCH] Be coherent in type usage
- no need to use off_t because it is read from strtoul()
- print unsigned int type correctly
When built with _FILE_OFFSET_BITS=64, off_t becomes an long long int
and was printed as an unsigned int which lead to a garbled output.
