Defined default values for baudrate, parity, stop bits, and data bits.
This removes complexity and obfuscation from the code.

This adds the CONFIG_UART_USE_RUNTIME_CONFIGURE guard to
disable the API function pointers if the kconfig is not enabled.
Both .configure and .config_get should only be usable if runtime
(re-)configuration of UART is needed.
Ifdef guards are added to drivers previously lacking this guard.
