platform: tegra: bwmgr: Fix debug macro build

Browse Source 
When NV_TEGRA264_BWMGR_DEBUG_MACRO_PRESENT is not defined the build
fails and the following errors are seen ...

 drivers/platform/tegra/tegra-bpmp-bwmgr.c:101:12: error:
  ‘tegra_bpmp_bwmgr_devfreq_target’ defined but not used
  [-Werror=unused-function]
  101 | static int tegra_bpmp_bwmgr_devfreq_target(struct device *dev,
                                       unsigned long *freq, u32 flags)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 drivers/platform/tegra/tegra-bpmp-bwmgr.c:37:12: error:
  ‘tegra_bpmp_bwmgr_max_freq_notifier’ defined but not used
  [-Werror=unused-function]
   37 | static int tegra_bpmp_bwmgr_max_freq_notifier(struct
                  notifier_block *nb, unsigned long action, void *ptr)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix this by ensuring the above functions are not defined if
NV_TEGRA264_BWMGR_DEBUG_MACRO_PRESENT is not defined.
