Rename SSD1306 driver to unified OLED name

git mv ssd1306_display_driver.c -> oled_display_driver.c;
rename the create_port entry point and the log TAG accordingly.
Pure rename -- all three OLED compatibles (solomon-systech,ssd1306,
solomon-systech,ssd1315, sino-wealth,sh1106) now dispatch through
oled_display_create_port.

The previous filename attributed a Sino Wealth controller (SH1106)
to Solomon Systech and was obsolete since the file started driving
multiple variants.
