drivers: nrfx: Add Kconfig checks for mutually exclusive peripherals

Browse source 
In Nordic SoCs, SPI and TWI peripherals with the same instance number
share certain resources and therefore cannot be used at the same time
(in nRF91 Series this limitation concerns UART peripherals as well).
This patch adds Kconfig checks ensuring that only one of such mutually
exclusive peripherals can be enabled.
