So far we only enabled one legacy serial port on the SMSC LPC47m superio chipset on Intel Crown Bay board. As the board also has dual PS/2 ports routed out, enable the keyboard controller which is i8042 compatible so that we can use PS/2 keyboard and mouse. In order to make PS/2 keyboard work with the VGA console, remove CONFIG_VGA_AS_SINGLE_DEVICE. To boot Linux kernel with PIC mode using PIRQ routing table, adjust the mask in the device tree to reserve irq12 which is used by PS/2 mouse.
