ps2port: `keyboard self test failed (got ab not 0xaa)`

[Paul Menzel]

Dear SeaBIOS folks,

On the laptop TUXEDO Book BU1406 (Clevo N240BU) with coreboot [1] and 
SeaBIOS master, the internal PS/2 keyboard often does not work.

SeaBIOS (version rel-1.13.0-45-g6ada228)
     […]

With MrChromebox’ commit bfdb3f86 (ps2port: adjust init routine to fix 
PS/2 keyboard issues) the PS/2 keyboard is not working either, but the 
log messages are a little different.
