drm/tyr: depend on `COMMON_CLK` to fix build error

Tyr needs `CONFIG_COMMON_CLK` to build:

error[E0432]: unresolved import `kernel::clk::Clk`
--> drivers/gpu/drm/tyr/driver.rs:3:5
|
3 | use kernel::clk::Clk;
| ^^^^^^^^^^^^^^^^ no `Clk` in `clk`

error[E0432]: unresolved import `kernel::clk::OptionalClk`
--> drivers/gpu/drm/tyr/driver.rs:4:5
|
4 | use kernel::clk::OptionalClk;
| ^^^^^^^^^^^^^^^^^^^^^^^^ no `OptionalClk` in `clk`

Thus add the dependency to fix it.
