add board pll kp, ki debug info

See merge request !9

Generalize lpdc_mdio_regs signals pll_sw_reset, pll_locked and aux_reset

See merge request !7

Add comments, make some functions void

it was copying data from softpll

Remove led_stat and led_link (unused).
Do not redefine a struct for SYSC (use the one from the header).
Renaming.

Note: I'm abusing the SFP deltaTX/deltaRX entries and just overriding them with bogus values adjusted only for the eRTM14's PHY TX asymmetry.

This is not the right way to handle the deltas. We need to separately provide the PHY delays and SFP delays to the PTP stack (and also probably drop the hardcoded bitslide parameter in ppsi). To be discussed.

Add calibration show

Remove deprecated API, use uint32_t for id, reduce code size

(afcz and wr2rf)

wr2rf and ertm14 uses lower values.

dev/rxts_calibrator: use the t24p value stored in flash if not out-of-range (fixes 50ps jumps regression)
