i2c: rk3x: add Kconfig dependency on COMMON_CLK

which introduced a dependency on clock rate notifiers. Now we get compiler errors if compiled without COMMON_CLK:

drivers/i2c/busses/i2c-rk3x.c: In function 'rk3x_i2c_clk_notifier_cb':
drivers/i2c/busses/i2c-rk3x.c:634:7: error: 'PRE_RATE_CHANGE' undeclared (first use in this function) [...]

But the driver has always depended on COMMON_CLK even if it compiled
- in fact it fails to probe without it. So add that as a Kconfig
dependency.

Wolfram,

here is a version with better commit msg in case you still want to take that instead of my quick fix.

Uwe, thanks for your comments!

Cheers,
Max

This line usually goes into the S-o-B block below. So maybe:

Commit 5a6f1566f6a0 ("i2c: rk3x: handle dynamic clock rate changes correctly") introduced a dependency ...

and then the Fixes line above your S-o-b.

Thanks for your quick turn around.

Uwe
