    loader: Instrument gfx_fb_fill with tslog
    
    Some systems boot absurdly slowly, apparently due to problems with
    UEFI framebuffer accesses being sluggish.  This does not fix the
    problem, but at least makes gfx_fb_fill show up as a large block
    in boot flamecharts, which will save time when the next user needs
    to identify why their system is booting slowly.
