This preps the code for merging common registers altogether.

- radio_rst was being asserted to reset the capture iface IDELAYs but
that was excessive and had adverse effects on the rest of the radio
- Replaced radio_rst with a localized IDELAYCTRL reset

- Everytime the LMK is configured, we do the following:
- Reset all LMK regs
- Wait for LMK lock
- Reset radio_clk PLL in FPGA
- Wait for FPGA PLL to lock
- Assert radio_rst which resets downstream radio logic
- This address the intermittent self-cal failures due to uncalibrated IDELAY taps
- Bumped FPGA compat to 12

- Added new PCIe and MB PIDs for new boards
- Added an error if MB PID is invalid

- Self-calibration routine steps through various values of LMK
delay to detect metastability in the SSCLK -> radio_clk crossing
and computes an ideal delay for the ADC clock.
- Self calibration is triggered at startup if the self_cal_adc_delay
device arg is specified

- Added DMA enabled states to DMA logic to allow for hardware data flushing during init.
- niusrprio_session will now check for FPGA busy before downloading

PPS on external input on X3xx
- Fixed behavior of PPS and clock references to be consistent and intuitive.
-- Added detection of clock reference and PPS.
-- Changed order of precedence to external, gpsdo, internal for default of clock and PPS.
-- Throws runtime error if the user requests a reference clock or PPS that is not present.
- Bumped FPGA compatibility to 4.
