Add gpio base address reading in the driver; in old code, it just
returns -1 to gpio->chip.base.

Signed-off-by: Hongwei Zhang <redacted>NAK, sorry. We never allow the device tree to specify this. First, it is a Linux-only base so it would have to be a "linux,..." property. Even if it is a Linux-only property, it is a bad idea. Only people using sysfs should have any need to specify global GPIO numbers. Don't use sysfs. Use the GPIO character device instead.
