[PATCH 14/20] media: atomisp: Remove atomisp_css_suspend()/_resume()

[Hans de Goede <hdegoede@xxxxxxxxxx>]

atomisp_css_suspend() is a 1:1 copy of atomisp_css_uninit() and
atomisp_css_resume() is a 1:1 copy of atomisp_css_init().

Remove the 2 copies and have their one caller just call
atomisp_css_uninit() / atomisp_css_init() instead.
