clk: Provide !COMMON_CLK dummy for devm_clk_rate_exclusive_get() 

mainline inclusion
from mainline-v6.9-rc5
commit 7f1dd39aedfccf60772328c5b88d56dbd39954c3
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IACTBX
CVE: CVE-2024-40965

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7f1dd39aedfccf60772328c5b88d56dbd39954c3



--------------------------------

To be able to compile drivers using devm_clk_rate_exclusive_get() also
on platforms without the common clk framework, add a dummy
implementation that does the same as clk_rate_exclusive_get() in that
case (i.e. nothing).
