Ok. But in case of non-DT boot if someone selects gptimers for both clkevt and
clksrc, both the name members will end up pointing to the same memory location.
To be specific, in the current code the clkevt timer name will point to the clksrc
name. This won't be noticeable during boot since the clkevt name gets printed
before it is over-written.
