Glenn Miles ff557c272c misc/pca9552: Let external devices set pca9552 inputs 
Allow external devices to drive pca9552 input pins by adding
input GPIO's to the model.  This allows a device to connect
its output GPIO's to the pca9552 input GPIO's.

In order for an external device to set the state of a pca9552
pin, the pin must first be configured for high impedance (LED
is off).  If the pca9552 pin is configured to drive the pin low
(LED is on), then external input will be ignored.

Here is a table describing the logical state of a pca9552 pin
given the state being driven by the pca9552 and an external device:

                   PCA9552
                   Configured
                   State

                  | Hi-Z | Low |
            ------+------+-----+
  External   Hi-Z |  Hi  | Low |
  Device    ------+------+-----+
  State      Low  |  Low | Low |
            ------+------+-----+
