dt-bindings: input: touchscreen: imagis: add missing minItems
The binding currently expects exactly 5 keycodes, which matches the
chip's theoretical maximum but probably not the number of touch keys on
any phone using the IST3032C. Add a minItems value of 2 to prevent
dt-validate complaints.
Also add another example to make sure the linux,keycodes property is
checked.
