There is no urgent need to get all board files to have empty
machine descriptors, I would not expect that to happen for
the more complex platforms like omap any time soon.

You currently use quite a number of callbacks:

DT_MACHINE_START(OMAP5_DT, "Generic OMAP5 (Flattened Device Tree)")
        .reserve        = omap_reserve,
        .smp            = smp_ops(omap4_smp_ops),
        .map_io         = omap5_map_io,
        .init_early     = omap5_init_early,
        .init_irq       = omap_gic_of_init,
        .handle_irq     = gic_handle_irq,
        .init_machine   = omap_generic_init,
        .timer          = &omap5_timer,
        .dt_compat      = omap5_boards_compat,
        .restart        = omap44xx_restart,
MACHINE_END

and I see nothing wrong with that. For simpler platforms that
after migrating out init_irq and init_timer have only one
or two callbacks left, it may be more interesting to actually
go all the way and remove all of them if possible.
