- Remove pipeline, CSR and IRQ because version x.y.z already incorporates
this information.
- Remove bond number because it is not used.
- Remove rev number because register was not implemented, always 0
- Add HW Rev ID register to replace rev number
- Add OTP config select to show the user configuration chosen by
the configurable GPIO pins on start-up

ptp: Add a ptp clock driver for IDT ClockMatrix.
The IDT ClockMatrix (TM) family includes integrated devices that provide
eight PLL channels. Each PLL channel can be independently configured as a
frequency synthesizer, jitter attenuator, digitally controlled
oscillator (DCO), or a digital phase lock loop (DPLL). Typically
these devices are used as timing references and clock sources for PTP
applications. This patch adds support for the device.

With 4.8.7 firmware, adjtime can change delta instead of absolute time,
which greately increases snap accuracy. PPS alignment doesn't have to

adding more debug logs, increasing snap accuracy for pre 4.8.7 firmware
and supporting new tcs2bin format.
