gpio: Fix lockdep warnings in gpiolib_{cdev,sysfs}_register()

A lockdep warning is reported in gpiolib-cdev driver:

  WARNING: drivers/gpio/gpiolib-cdev.c:2735 at
  gpiolib_cdev_register+0x114/0x140, CPU#1: swapper/0/1

    gpiochip_add_data_with_key from devm_gpiochip_add_data_with_key+0x20/0x5c

This is because the SRCU wasn't held in gpiolib_cdev_register() when the
caller is from gpiochip_add_data_with_key() instead of
gpiochip_setup_devs().  gpiochip_sysfs_register() shares the similar
concern.

Given that both gpiolib_cdev_register() and gpiochip_sysfs_register()
are only called from gpiolib but no external users.  Remove the lockdep
checks to fix the warnings.
