[KOS] keyboard

[Christian G. <ko...@ya...>]

Hi,

when I connected a German keybaord it gave me just scancodes in the high 
byte.

Looking at kernel/arch/dreamcast/hardware/maple/keyboard.c I see that 
only Japanese and
US keyboards are supported. All other keyboards just return scancodes.

I propose the following change for unsupported keyboards to let them at 
least appear as
an US keyboard. I think that's better than returning scancodes for keys 
which were previously
(in older KOS versions) returned as ASCII.

And, I want to support German keyboards. They identify as region #4.
The 'keymaps' array in kernel/arch/dreamcast/hardware/maple/keyboard.c 
just has entries
for (regions) #1 and #2. I don't know what region #3 is. I'd add it as 
just zeroes, and add
a check in above patch to map it to an US keyboard,

What do you think?
