xtensa: remove duplicate CONFIG_HOTPLUG definition

As part of the plan to remove CONFIG_HOTPLUG, it was found that xtensa
duplicates this config option for no reason (it's already defined as part of
init/Kconfig).  This patch removes it from the xtensa-only Kconfig file.

-	  Say Y here if you want to plug devices into your computer while
-	  the system is running, and be able to use them quickly.  In many
-	  cases, the devices can likewise be unplugged at any time too.
-
-	  One well known example of this is PCMCIA- or PC-cards, credit-card
-	  size devices such as network cards, modems or hard drives which are
-	  plugged into slots found on all modern laptop computers.  Another
-	  example, used on modern desktops as well as laptops, is USB.
-
-	  Enable HOTPLUG and build a modular kernel.  Get agent software
-	  (from <http://linux-hotplug.sourceforge.net/>) and install it.
-	  Then your kernel will automatically call out to a user mode "policy
-	  agent" (/sbin/hotplug) to load modules and set up software needed
-	  to use devices as you hotplug them.
