ARM: 8743/1: bL_switcher: add MODULE_LICENSE tag

Without this tag, we get a build warning:

WARNING: modpost: missing MODULE_LICENSE() in arch/arm/common/bL_switcher_dummy_if.o

For completeness, I'm also adding author and description fields.

Replace <asm/uaccess.h> with <linux/uaccess.h> globally

This was entirely automated, using the script by Al:

PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>'
sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \
$(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h)

to do the replacement at the end of the merge window.

miscdevice: Add helper macro for misc device boilerplate

Many modules call misc_register and misc_deregister in its module init
and exit methods without any additional code. This ends up being
boilerplate. This patch adds helper macro module_misc_device(), that
replaces module_init()/ module_exit() with template functions.

This patch also converts drivers to use new macro.

Change since v1:
Add device.h include in miscdevice.h as module_driver macro was not
available from other include files in some architectures.

where <cpuid> is the logical CPU number, and <clusterid> is 0 for the
first cluster and 1 for the second cluster.
