gpio: pca953x: Add optional reset gpio control
Add optional reset-gpios pin control. If present, de-assert the
specified reset gpio pin to bring the chip out of reset.
v2:
- Specify that reset signal to PCA953x chip is active low, in
binding doc.
- reorder includes in gpio-pca953x.c.
- remove dev_err() on devm_gpiod_get_optional() error return.
