During the reboot_ec command, the keyboard state is lost after jump.
We need to restore info including:
- code set
- controller_ram[0]:
- XLATE
- KB/TP disabled
- KB/TP IRQ enabled
Remove the un-necessary keyboard_init() function.
BUG=chrome-os-partner:9102
TEST=tested on link.
EC runs on A
% ectool reboot_ec A
keyboard still working
% ectool reboot_ec RO
keybaord still working
% ectool reboot_ec RO
keybaord still working
ESC + power yo reset all system
repeat above steps and the keyboard keeps working.
