nokia105-emu: Nokia 105 firmware emulation

nokia105-emu runs a Nokia 105 TA-1423 firmware dump from boot ROM to a usable menu interface. Unicorn emulates the ARM926EJ-S CPU, while Python modules model the SC6531E interrupt controller, flash, display, keypad, power management and other peripherals based on firmware behaviour. The user supplies the phone’s own flash and boot ROM images.
