gpio: stp-xway: simplify error handling in xway_stp_probe()
Return early if devm_gpiochip_add_data() returns an error instead of
having two consecutive "if (!ret) ..." statements.
Also make xway_stp_hw_init() return void because it unconditionally
returns 0. While here also update the kerneldoc comment for
xway_stp_hw_init().
These changes makes the error handling within the driver consistent.
No functional changes intended.
