[PATCH 3/9] arm/term: Fix linking error due multiple ps2_state definitions

[Javier Martinez Canillas]

When building with --target=arm-linux-gnu --with-platform=coreboot
a linking error occurs caused by multiple definitions of the
ps2_state variable.

Mark them as static since they aren't used outside their compilation unit.
