Currently pm_pr_dbg() is used to filter kernel pm debug messages based
on pm_debug_messages_on flag. The problem is if we enable/disable this
flag it will affect all pm_pr_dbg() calls at once, so we can't
individually control them.
This patch changes pm_pr_dbg() implementation as such:
- If pm_debug_messages_on is enabled, print the message.
- If pm_debug_messages_on is disabled and CONFIG_DYNAMIC_DEBUG is
enabled, only print the messages explicitly enabled on
/sys/kernel/debug/dynamic_debug/control.
- If pm_debug_messages_on is disabled and CONFIG_DYNAMIC_DEBUG is
disabled, don't print the message.
