dt-bindings: iio: adc: samsung,exynos: Drop touchscreen support

With last user of touchscreen via ADC (S3C24xx SoC) gone, drop the
unused has-touchscreen property and optional touchscreen interrupt for
samsung,s3c6410-adc. The samsung,s5pv210-adc is the only platform
having two interrupts, so add a constrain for that.
