falco: add rtd2132 settings to device tree
Now that the rtd2132 device has the full settings the
panel timings need to be implemented. Sadly, the Tx timings
in the rtd2132 aren't 1:1 with the panel's Tx timings. Below
is the table equivalent:
RTD2132 | Falco Panel
--------+------------
T1 | T2
--------+------------
T2 | T8+T10+T12
--------+------------
T3 | T14
--------+------------
T4 | T15
--------+------------
T5 | T9+T11+T13
--------+------------
T6 | T3
--------+------------
T7 | T4
--------+------------
