Modify the phc_ctl utility to add a helpful get_pins_cfg command to display the current pin configuration.
This is a follow up of a previous v2 I sent a long time ago at [1], but includes a couple of additional cleanups. First, I modified phc.c to dynamically check and use PTP_PIN_SETFUNC2 if available, falling back to PTP_PIN_SETFUNC if its not supported (-ENOTTY return value). Second, I expose phc_get_caps and use this instead of re-inventing this again in phc_ctl.c Finally, the actual implementation is in the 3rd patch. In a similar way to PTP_PIN_SETFUNC2, I use PTP_PIN_GETFUNC2 and fallback to PTP_PIN_GETFUNC in the case of -ENOTTY return value, and use the phc.c helper file instead of open coding equivalent functions. This version should fix the issues with missing values and also dynamically supports the newer ioctls when available rather than relying on compiler time checks.
