clk: imx: Add some delay before deassert the reset

Browse source

Some of the PCCs on i.MX8ULP have a sw_rst bit to control the peripheral
reset through SW method. For peripherals like GPU that need sync reset,
some delay is necessary befere & after release the reset to make sure the
HW is reset into a known status. So add some delay before & after release
reset.
