scripts/gdb: print cached rate in lx-clk-summary

2019-05-15T02:52:52Z

The clk rate is always stored in clk_core but might be out of date and require calls to update from hardware. Deal with that case by printing a (c) suffix.

scripts/gdb: add $lx_clk_core_lookup function

2019-05-15T02:52:52Z

Finding an individual clk_core requires walking the tree which can be quite complicated so add a helper for easy access.

scripts/gdb: initial clk support: lx-clk-summary

2019-05-15T02:52:52Z

Add an lx-clk-summary command which prints a subset of /sys/kernel/debug/clk/clk_summary. This can be used to examine hangs caused by clk not being enabled.
