soc: arm: add support for nuvoton numicro m48x series Add initial support for nuvoton numicro m48x SoC series, basic init and uart functionality are covered with gpio and clock directly relies on HAL. Signed-off-by: Saravanan Sekar <saravanan@linumiz.com>

soc: arm: rename soc/arm/nuvoton as soc/arm/nuvoton_numicro We try to reduce the ambiguity between 'soc/nuvoton/' and 'soc/nuvoton_npcx' folders. Most if soc vendors name their soc folder by the company name with SOC_FAMILY suffix instead of the company name directly. It is clearer if the soc company has different product lines that aim to specific markets. In this CL, the 'numicro' suffix is used for Nuvoton Microcontroller production line. It distinguishes the 'npcx' suffix that used for Nuvoton Embedded Controller (EC) of Notebook PC product line. Signed-off-by: Mulin Chao <mlchao@nuvoton.com>
