[PATCH] arm-coreboot: Declare global struct ps2_state as static so symbols don't cause link failure

[Glenn Washburn <development@efficientek.com>]

This appears to be a new issue surfaced by switching from gcc 9.3.0 to
10.1.0 cross compiling toolchain. When linking these two object files
together, there is an error generated: "multiple definition of `ps2_state'".
This only appears to be an issue when --target=arm-linux-gnueabi and
--with-platform=coreboot. There's no need for these structs to have global
as opposed to file scope, so declaring them as static fixes this issue.
