James Clark 6c75940eb7 coresight: Extend width of timestamp format attribute
'timestamp' is currently 1 bit wide for on/off. To enable setting
different intervals, extend it to 4 bits wide. Keep the old bit position
for backward compatibility ("deprecated_timestamp") but don't publish in
the format/ folder. It will be removed from the documentation and can be
removed completely after enough time has passed.

ETM3x doesn't support different intervals, so validate that the value is
either 0 or 1.

Tools that read the bit positions from the format/ folder will continue
to work as before, setting either 0 or 1 for off/on. Tools that
incorrectly didn't do this and set the ETM_OPT_TS bit directly will also
continue to work because that old bit is still checked.

This avoids adding a second timestamp attribute for setting the
interval. This would be awkward to use because tools would have to be
updated to ensure that the timestamps are always enabled when an
interval is set, and the driver would have to validate that both options
are provided together. All this does is implement the semantics of a
single enum but spread over multiple fields.
