[0/2] gdb/scripts: Improve lx-clk-summary

Message

The earlier series adding clk support to gdb/scripts was quickly
accepted but some concerns were raised by Stephen Boyd so this series
attempts to address them.

Link to previous series: https://lkml.org/lkml/2019/4/22/55

This is not a v2 and squashing is not expected.

Fields other than clk rate not covered because they're much more rarely
used and cache logic can get more complicated and brittle.

LX_GDBPARSED is used in constants.py.in because python does not
understand C integer literal suffixes like the "1UL" from the definition
of BIT() used by CLK_GET_RATE_NOCACHE. Alternative workarounds would be
hacking away UL suffixes with sed or redefining BIT&co but relying on
gdb evaluation is easier and much more flexible.
