Support KBC I8042_TEST_KB_PORT (0xab) command.
Lack of this command could make u-boot pc_keyb.c failed to init (see
lines around line 143 of u-boot/files/drivers/input/pc_keyb.c).
static char * kbd_initialize(void)
{
...
kbd_write_command_w(KBD_CCMD_KBD_TEST);
if (kbd_wait_for_input() != 0x00)
return "Kbd: interface failed self test";
