gpio: ts4800: Remove duplicate code to handle 'ngpios' property

The gpio_generic_chip_init() handles the 'ngpios' property and
assigns the respective field in struct gpio_chip either with
the value of it, or, if not found, with the default based on
the register size. There is no need to repeat this in the driver.
