serial: Introduce new mcux lpuart shim driver Adds a shim layer around the mcux lpuart driver to adapt it to the Zephyr serial interface. NXP has multiple uart hardware blocks that implement different features and have different register maps. The k64 has a uart block called 'uart', while the kw41 has a uart block called 'lpuart' (low power uart). The MCUXpresso SDK provides separate drivers for each type of uart block but with similar software interfaces. As a result, there are also separate shim drivers in Zephyr. There is a 1:1:1 relationship between hardware block, mcux driver, and mcux shim driver. Because we now have two mcux shim drivers for the uart interface, a new naming convention is created: <interface>_mcux_<hw block> Where <interface> is the name of the Zephyr interface, in this case 'uart'. This convention is not new. <hw block> is the name of the NXP hardware block, in this case 'lpuart'. This is the new part, and distinguishes different hardware blocks for the same interface.

serial: Refactor mcux lpuart shim driver to use clock control interface Refactors the mcux lpuart shim driver to use the clock control interface instead of calling CLOCK_GetFreq() directly. This will allow SoCs with different clock architectures to reuse this driver. Signed-off-by: Maureen Helm <maureen.helm@nxp.com>

serial: introduce SERIAL_SUPPORT_INTERRUPT Kconfig option As not all drivers support interrupts we don't have a means to know if we can allow UART_INTERRUPT_DRIVEN to be enabled and thus various Kconfig options that select UART_INTERRUPT_DRIVEN. Some drivers have a interrupts, however not all do. So introduce a Kconfig option to let us know what the driver actually supports. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
