iio: stx104: Add X86 dependency to STX104 Kconfig option

The Apex Embedded Systems STX104 DAC driver expects the STX104 device to
be I/O port-mapped addressable on an X86 platform. This patch adds an
explicit X86 dependency to the STX104 configuration option to prevent
building on non-X86 architectures.
