[PATCH v7 26/26] gpio/omap: add dbclk aliases for all gpio modules

Unless the dbclk aliases are assigned, clk_get(bank->dev, "dbclk")
would not fetch the associated clock handle. As a result, we would
not be able to turn on/off the debounce clock. This was preventing
the gpio modules going to low power mode whenever dbclk is enabled.
