Merge tag 'imx-dt-clkdep-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/dt

i.MX device tree changes with clock dependency:
 - Add clock for i.MX6UL GPIO blocks

* tag 'imx-dt-clkdep-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux:
  ARM: dts: imx6ul: add GPIO clocks
  clk: imx6ul: remove clks_init_on array
  clk: imx6ul: add GPIO clock gates
  dt-bindings: clock: imx6ul: Do not change the clock definition order
