services: Improve the upower-service-type. 

Add a description and default value. Switch the documentation to mention the
service-type and the configuration record, rather than the upower-service
procedure.

* gnu/services/desktop.scm (upower-service-type)[description, default-value]:
Define these fields.
(%desktop-services): Change (upower-service) to (service upower-service-type).
* doc/guix.texi (Desktop Services): Update the upower service documentation.

@deftp {Data Type} upower-configuration
Data type representation the configuration for UPower.
@table @asis
@item @code{upower} (default: @var{upower})
Package to use for @code{upower}.
@item @code{watts-up-pro?} (default: @code{#f})
Enable the Watts Up Pro device.
@item @code{poll-batteries?} (default: @code{#t})
Enable polling the kernel for battery level changes.
@item @code{ignore-lid?} (default: @code{#f})
Ignore the lid state, this can be useful if it's incorrect on a device.
@item @code{use-percentage-for-policy?} (default: @code{#f})
Whether battery percentage based policy should be used. The default is to use
the time left, change to @code{#t} to use the percentage.
@item @code{percentage-low} (default: @code{10})
When @code{use-percentage-for-policy?} is @code{#t}, this sets the percentage
at which the battery is considered low.
@item @code{percentage-critical} (default: @code{3})
When @code{use-percentage-for-policy?} is @code{#t}, this sets the percentage
at which the battery is considered critical.
@item @code{percentage-action} (default: @code{2})
When @code{use-percentage-for-policy?} is @code{#t}, this sets the percentage
at which action will be taken.
@item @code{time-low} (default: @code{1200})
When @code{use-time-for-policy?} is @code{#f}, this sets the time remaining in
seconds at which the battery is considered low.
@item @code{time-critical} (default: @code{300})
When @code{use-time-for-policy?} is @code{#f}, this sets the time remaining in
seconds at which the battery is considered critical.
@item @code{time-action} (default: @code{120})
When @code{use-time-for-policy?} is @code{#f}, this sets the time remaining in
seconds at which action will be taken.
@item @code{critical-power-action} (default: @code{'hybrid-sleep})
The action taken when @code{percentage-action} or @code{time-action} is
reached (depending on the configuration of @code{use-percentage-for-policy?}).
