[PATCH 03/12] mach-sc5xx: Kconfig: Make EZKIT and EZLITE carriers mutually exclusive

[Greg Malysa]

Support for the SOM-CRR variants introduces library level changes that
are not modelled in the device tree. As a result they cannot both be
selected at the same time, so this updates the dependency in Kconfig to
prevent them from being enabled together.
