uhd: change default into option flag in register definition

This adds support for read only registers in generated interfaces.

For this the default is extended to an option string. The old format
is still supported for backward compability, so if options string is
just a number it will be handled as a writable number.

The option string is a comma separated list with key=value pairs. The
value is optional and treated as None if missing.

common.py now allows to pass in **kwargs to the generate method which
is used by gen_zbx_cpld_regs.py to pass a filter function for registers
used by mpm only.

get_all_addr now has an additional (optional, defaults to false) flag
to indicate whether read only addresses are to be returned or not.
It also supports type generic for the result to align with
get_changed_addr function.

The ZBX CPLD CTRL map is adapted accordingly to reflect read only
registers. The power registers are flagged as MPM scope only (and not
used in ZBX CPLD control of UHD).
