This commit has no practical effect but cleanup. I made it
with sed like this:

  git grep -l '[ \t]$' | xargs sed -i 's/[ \t]*$//'

However, I had to manually restore doc/wrpc_mon.png after the fact.
Similarly, I restored the include/hw/*regs.h files, as they
are (most likely) auto-generated.

Tidy up printing at startup

Read the MAC address either from EEPROM or sensor ID (preferring EEPROM).

rewrote pps_gen driver (to match the libswitchhw one), removed remaining references to UTC timescale
