gpio fixes for v5.17-rc4

- use sleeping variants of GPIO accessors where needed in gpio-aggregator
- never return kernel's internal error codes to user-space in gpiolib core
- use the correct register for reading output values in gpio-sifive
- fix line hogging in gpio-sim
gpio: sim: fix hogs with custom chip labels

We always assign the default device name as the chip_label in hog
structures which makes it impossible to assign hogs to chips. Let's
first check if a custom label was set and then copy it instead of the
default device name.
