[PATCH] staging: wfx: silence symbol 'wfx_get_ps_timeout' was not declared warning

[Ashish Kalra]

Upon running sparse, "warning: symbol 'wfx_get_ps_timeout' was not declared.
Should it be static?" and "warning: symbol 'wfx_update_pm' was not declared.
Should it be static?" is brought to notice for this file.  static keyword
should be added to prevent this warning. let's add it to make it cleaner and
silence the Sparse warning.
