On some x86 tablets with a silead touchscreen the windows logo on the

Detect this and report a KEY_LEFTMETA press when this happens. Note for
now we only respond to the Y coordinate bits 12-15 containing 0x01, on some
tablets *without* a capacative button I've noticed these bits containing
capacitive
0x04 when crossing the edges of the screen.

I believe this means this is ready to be merged now. It would be nice
if we could still get this into 4.15 for rc2 (it is a fix in a way).
