coccicheck complains about the use of snprintf() in sysfs
show functions.
drivers/hwmon/ina3221.c:701:8-16: WARNING: use scnprintf or sprintf
This results in a large number of patch submissions. Fix it all in
one go using the following coccinelle rules. Use sysfs_emit instead
of scnprintf or sprintf since that makes more sense.

While at it, remove unnecessary braces and as well as unnecessary
else after return statements to address checkpatch warnings in the
resulting patch.

Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code,
to improve readability, and to reduce the chance of inconsistencies.
Also replace any remaining S_<PERMS> in the driver with octal values.
The conversion was done automatically with coccinelle. The semantic patches

The vexpress hwmon implementation is currently just called vexpress.
This is a problem because it clashes with another module with the same
name in regulators.
This patch renames the vexpress hwmon implementation to vexpress-hwmon
so that there will be no clash in the module namespace.
