ARM: LPC32xx: DT conversion of Standard UARTs
This patch switches from static serial driver initialization to devicetree configuration. This way, the Standard UARTs of the LPC32xx SoC can be enabled individually via DT. E.g., instead of Kconfig configuration, the phy3250.dts activates UARTs 3 and 5. Signed-off-by: Roland Stigge <stigge@antcom.de> Tested-by: Alexandre Pereira da Silva <aletes.xgr@gmail.com>
