Kernel/HID: Fix PS2 keyboard scan code tables
We do this by implementing the following fixes: - The Key_Plus is assigned to a proper map entry index now which is 0x4e both on the keypad and non-keypad keys. - Shift+Q now prints out "Q" properly on scan code set 2. - Key BackSlash (or Pipe on shift key being pressed down) is now working properly as well. - Key_Pipe (which is "|" for en-US layout) is now working in scan code set 2. - Numpad keys as well as the decimal separator key are working again.
