one or the other.

We always register these two together, so move meter_rw_attrs into
meter_ro_attrs and use the same for both since we no longer have two
register_attr paths.

We don't need both, when we can just key the read/write off of the
presence of the .set member.

In some configurations, BUG() does not result in an endless loop but returns
to the caller. This results in the following compiler warning:
drivers/hwmon/acpi_power_meter.c: In function 'show_str':
drivers/hwmon/acpi_power_meter.c:380: warning: 'val' may be used uninitialized in this function
Fix the warning by setting val to an empty string after BUG().

Similar to a30dcb4f which fixed asus_atk0110.ko, I recently received a
bug report from someone hitting the same issue in acpi_power_meter.
[ 13.963168] power_meter ACPI000D:00: Found ACPI power meter.
[ 13.963900] BUG: key ffff8802161f3920 not in .data!

[ 13.963915] WARNING: at kernel/lockdep.c:2986
lockdep_init_map+0x52f/0x560()
So let's fix that up for them by statically declaring the
lockdep_class_key.

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

As discussed earlier, the ACPI power meter driver would better live
in drivers/hwmon, as its only purpose is to create hwmon-style
interfaces for ACPI 4.0 power meter devices. Users are more likely to
look for it there, and less likely to accidentally hide it by
unselecting its dependencies.
