iio: imx8qxp-adc: fix dependency to the intended ARCH_MXC config

Commit 1e23dca ("iio: imx8qxp-adc: Add driver support for NXP IMX8QXP
ADC") adds the config IMX8QXP_ADC for this new driver, which depends on
the non-existing config ARCH_MXC_ARM64.

Hence, ./scripts/checkkconfigsymbols.py warns:

  ARCH_MXC_ARM64
  Referencing files: drivers/iio/adc/Kconfig

Probably, the existing config ARCH_MXC is intended to be referred here.
So, repair the dependency to refer to that config.
