[PATCH v1 1/2] gpio: realtek-otto: amend ctrl struct docs

[Sander Vanheule]

Commit 512c5be35223 ("gpio: realtek-otto: Support reversed port
layouts") and commit 95fa6dbe58f2 ("gpio: realtek-otto: Support per-cpu
interrupts") updated the realtek_gpio_ctrl struct with new fields, but
the associated kernel-doc comment was not updated accordingly.
