counter: microchip-tcb-capture: Handle Signal1 read and Synapse

commit d917a62af81b133f35f627e7936e193c842a7947 upstream.

The signal_read(), action_read(), and action_write() callbacks have been
assuming Signal0 is requested without checking. This results in requests
for Signal1 returning data for Signal0. This patch fixes these
oversights by properly checking for the Signal's id in the respective
callbacks and handling accordingly based on the particular Signal
requested. The trig_inverted member of the mchp_tc_data is removed as
superfluous.

Fixes: 106b104137fd ("counter: Add microchip TCB capture counter")
