drivers/rtt: overrite RTT_MAX_VALUE and RTT_FREQUENCY for mock

Browse Source 
mock_rtt relies on setting mock values for RTT_MAX_VALUE and
RTT_FREQUENCY. Platforms with a rtt will already define these
values which leads to mock_rtt working with different values than
rtt_rtc.

This commit changes the ifdef logic so that when using mock_rtt
RTT_MAX_VALUE and RTT_FREQUENCY are redefined.
