tests: build_all: eeprom: change config for compatibility

Since the old configuration set a sensor initialization priority to 60,
we faced a conflict between sensor and regulator initialization priorities.
I think the best approach is to always use a lower priority if the
component has dependencies. If this is a specific case, maybe a .conf file
is needed for the board. The new .conf file will then be more generic.
