Subject: clk: tegra: Fix build error without CONFIG_PM_SLEEP

Git-commit: 07b293c5b01483f3c65372e72e62a2ee559ce1cf
Patch-mainline: v5.5-rc1
References: jsc#SLE-9391,jsc#SLE-9388,jsc#SLE-10608

If CONFIG_PM_SLEEP is n, build fails:

drivers/clk/tegra/clk-tegra210.c:3426:13: error:
 tegra210_clk_suspend undeclared here (not in a function); did you mean tegra_clk_ndspeed?
  .suspend = tegra210_clk_suspend,
             ^~~~~~~~~~~~~~~~~~~~
             tegra_clk_ndspeed
drivers/clk/tegra/clk-tegra210.c:3427:12: error:
 tegra210_clk_resume undeclared here (not in a function); did you mean tegra210_clk_suspend?
  .resume = tegra210_clk_resume,

Use ifdef to guard this.
