Subject: [PTCH -next] staging/iio: fix ring buffer build

From: Randy Dunlap <randy.dunlap@...cle.com>

max1363 uses both the iio hardware ring buffer and software
ring buffer interfaces, but its Makefile and Kconfig do not
reflect that usage, so its build breaks.  Add a new Kconfig
symbol to reflect that usage and change max1363.h & Makefile
to use the new Kconfig symbol.
