			* modify oled_driver to support SH1106 also: - improve mechanism to specify which OLED IC we use - comment calc_bounds() - give OLED_COLUMN_OFFSET a default value - inline comment re: OLED MEMORY_MODE and SH1106 - update docs/feature_oled_driver.h for SH1106 support and related changes - docs: OLED: note we have tested SSD1306 on ARM boards (per @XScorpion2) - define out MEMORY_MODE when using SH1106 OLED driver * document that SSD1306 128x64 on AVR works Per @XScorpion2: https://github.com/qmk/qmk_firmware/pull/5787#discussion_r291837842
