[PATCH v4 10/12] gpio/omap: fix missing dataout context save in _set_gpio_dataout_reg

[Tarun Kanti DebBarma]

There are two functions, _set_gpio_dataout_reg() and _set_gpio_dataout_mask()
which writes to dataout register and the dataout context must be saved.
It is missing in the first function, _set_gpio_dataout_reg(). Fix this.
