The 'dev' parameter in the zynq_gpio_get_bank_pin function was not
described in its kernel-doc comment block, leading to a Sparse warning.
drivers/gpio/zynq_gpio.c:194: warning: Function parameter or member 'dev'
not described in 'zynq_gpio_get_bank_pin'
Add a description for the 'dev' parameter to satisfy the documentation
requirements and improve code clarity for this function.
