[PATCH 2/2] iio: adc: Kconfig: add kfifo dependency to fix module build

[Arthur-Prince <r2.arthur.prince@gmail.com>]

Add dependency to Kconfig’s ti-ads1298 because compiling it as a module
failed with an undefined kfifo symbol. Building the full kernel passed
since kfifo was enabled globally. Selecting IIO_KFIFO_BUFFER in 
ti-ads1298’s Kconfig, as done by other IIO ADC drivers, now ensures kfifo
buffer support is included for module builds.
