Add basic support for Airoha EN7523, enough for booting to console.
The UART is basically 8250-compatible, except for the clock selection.
A clock-frequency value is synthesized to get this to run at 115200 bps.

+
+ The clock driver uses it to read and configure settings of the

+
+ Each clock is assigned an identifier and client nodes use this identifier
+ to specify which clock they consume.
+
+ All these identifiers can be found in:
+ [1]: <include/dt-bindings/clock/en7523-clk.h>.

This driver only registers fixed rate clocks, since the clocks are fully
initialized by the boot loader and should not be changed later, according
to Airoha.
