boards: arm: add initial support for efr32bg22_brd4184b
This adds basic support for 'B' revision of the Silicon Labs EFR32BG BRD4184 (Thunderboard BG22) board. Due to missing drivers, some of the on-board peripherals are currently unsupported: - Silicon Labs Si7021 relative humidity and temperature sensor - Vishay VEML6035 ambient light sensor - Knowles SPK0641HT4H-1 MEMS microphones - TDK InvenSense ICM-20648 6-axis inertial sensor Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>
