[WIP ]linux-iot2050: Add the support for the SM variant

[Commit message need refine] Add the support for the everlight pm16d17 sensor This sensor is used to detect the distance of the cover, when the cover of the iot2050 open or close, the emiter strength would change. According this change to judge whether the cover open or close. Add "wkup_gpio0-base" to let mraa get button gpio. Remove arduino dts on iot2050 SM variants Signed-off-by: chao zeng <[email protected]> Signed-off-by: Li Hua Qian <[email protected]> Signed-off-by: Baocheng Su <[email protected]>
