[PATCH] scripts/gdb: Fix invocation when CONFIG_COMMON_CLK is not set

[Fabiano Rosas]

CLK_GET_RATE_NOCACHE depends on CONFIG_COMMON_CLK. Importing
constants.py when CONFIG_COMMON_CLK is not defined causes:

  (gdb) lx-symbols
  (...)
    File "scripts/gdb/linux/proc.py", line 15, in <module>
      from linux import constants
    File "scripts/gdb/linux/constants.py", line 2, in <module>
      LX_CLK_GET_RATE_NOCACHE = gdb.parse_and_eval("CLK_GET_RATE_NOCACHE")
  gdb.error: No symbol "CLK_GET_RATE_NOCACHE" in current context.

Fixes: e7e6f462c1be ("scripts/gdb: print cached rate in lx-clk-summary")
