Extend the driver implementation to support PTP pins on E810-T and
derivative devices.

E810-T adapters are equipped with:
- 2 external bidirectional SMA connectors
- 1 internal TX U.FL shared with SMA1
- 1 internal RX U.FL shared with SMA2

The SMA and U.FL configuration is controlled by the external
multiplexer.

E810-T Derivatives are equipped with:
- 2 1PPS outputs on SDP20 and SDP22
- 2 1PPS inputs on SDP21 and SDP23

v2:
* Fix code style errors
* Change pca9575_handle type returned by ice_get_pca9575_handle to u16

Maciej Machnikowski (4):
  ice: Refactor ice_aqc_link_topo_addr
  ice: Implement functions for reading and setting GPIO pins
  ice: Add support for SMA control multiplexer
  ice: Implement support for SMA and U.FL on E810-T
