The Gemini now has a proper clock driver and a proper PCLK
assigned in its device tree. Drop the Gemini-specific hacks
to look up the system speed and rely on the clock framework
like everyone else.

We need to also prepare and enable the clock we are using to get
the right reference count and avoid it being shut off.

The plain Faraday FTTMR010 timer needs a clock to figure out its
tick rate, and the gemini reads it directly from the system
controller set-up. Split the init function and add two paths for
the two compatible-strings. We only support clocking using PCLK
because of lack of documentation on how EXTCLK works.
The Gemini still works like before, but we can also support a
generic, clock-based version.

After some research it turns out that the "Gemini" timer is
actually a generic IP block from Faraday Technology named
FTTMR010, so as to not make things too confusing we need to
rename the driver and its symbols to make sense.
The implementation remains the same in this patch but we fix
the copy-paste error in the timer name "nomadik_mtu" as we're
at it.
