The i.MX93 11x11 EVK fails to boot with following error:

 Model: NXP i.MX93 11X11 EVK board

 ### ERROR ### Please RESET the board ###

That's because since commit e7ff54d96303 ("imx93_evk: defconfig: add adc
support") CONFIG_ADC_IMX93 is enabled but CONFIG_ADC is not.
Fix this by enabling CONFIG_ADC in imx93_11x11_evk_defconfig.

Make sure this situation won't happen again in future i.MX93 defconfig by
making CONFIG_ADC_IMX93 depend on CONFIG_ADC.
