ACPI: WMI: Improve Kconfig description
As Pavel Machek has pointed out, the Kconfig entry for WMI is pretty
non-descriptive.
Rewrite it so that it explains what ACPI-WMI is, and why anyone
would want to enable it.
Many thanks to Ray Lee for ideas on this.

+ This driver adds support for the ACPI-WMI (Windows Management
+ Instrumentation) mapper device (PNP0C14) found on some systems.
- NOTE: You will need another driver or userspace application on top of
- this to actually use anything defined in the ACPI-WMI mapper.
+ ACPI-WMI is a proprietary extension to ACPI to expose parts of the
+ ACPI firmware to userspace - this is done through various vendor
+ defined methods and data blocks in a PNP0C14 device, which are then
+ made available for userspace to call.
+
+ The implementation of this in Linux currently only exposes this to
+ other kernel space drivers.
+
+ This driver is a required dependency to build the firmware specific
+ drivers needed on many machines, including Acer and HP laptops.
+
+ It is safe to enable this driver even if your DSDT doesn't define
+ any ACPI-WMI devices.
