tty: serial: atmel: Add COMMON_CLK dependency to SERIAL_ATMEL
Now that the driver makes use of `__clk_is_enabled()` in order to
know whether a `clk_disable_unprepare()` is needed or not on the
GCLK, a new dependency has been introduced: COMMON_CLK. If this
`CONFIG_COMMON_CLK` is not enabled, whatever config may have this
driver enabled without COMMON_CLK then an undefined reference to
`__clk_is_enabled()` will be issued by the linker.
Thus, make sure that, unless `CONFIG_COMMON_CLK` is enabled, this
driver is not compiled.
Fixes: 5e3ce1f26129 ("tty: serial: atmel: Make the driver aware of the existence of GCLK")
