So, devctrl is a syscon device and this DTS introduce several
identical GPIO descriptions?

On my opinion this should be placed in the gpio-syscon.c,
where you can add support for ti,keystone-dsp0{..7}-gpio.
Such change will avoid parts 2 and 3 of this patch.

static const struct syscon_gpio_data ti_keystone_dsp0_gpio = {
  .compatible = "ti,keystone-syscon",
  .dat_bit_offset = 0x240 * 8,
  ...
  .set = etc...
};
