[media] DocBook: better document FE_SET_VOLTAGE ioctl
Use the proper format for FE_SET_VOLTAGE documentation and fix
the documentation. The description for the enum is not 100%,
and it is missing the voltage off value.
Also, it is better to keep the enum description together with
the ioctl, as both are used together.

+<para>This ioctl allows to set the DC voltage level sent through the antenna
+ cable to 13V, 18V or off.</para>
+<para>Usually, a satellital antenna subsystems require that the digital TV
+ device to send a DC voltage to feed power to the LNBf. Depending on the
+ LNBf type, the polarization or the intermediate frequency (IF) of the LNBf
+ can controlled by the voltage level. Other devices (for example, the ones
+ that implement DISEqC and multipoint LNBf's don't need to control the
+ voltage level, provided that either 13V or 18V is sent to power up the
+ LNBf.</para>
+<para>NOTE: if more than one device is connected to the same antenna,
+ setting a voltage level may interfere on other devices, as they may lose
+ the capability of setting polarization or IF. So, on those
+ cases, setting the voltage to SEC_VOLTAGE_OFF while the device is not is
+ used is recommended.</para>
