[PATCH] gpio: Correct kernel-doc inconsistency

[Colton Lewis <colton.w.lewis@xxxxxxxxxxxxxx>]

Silence documentation build warnings by correcting kernel-doc comment
for gpiochip_add_data function.

./include/linux/gpio/driver.h:512: warning: Function parameter or member 'gc' not described in 'gpiochip_add_data'
./include/linux/gpio/driver.h:512: warning: Excess function parameter 'chip' description in 'gpiochip_add_data'
