Despite commit 55020c8056 ("of: Add vendor prefix for ON Semiconductor
Corp.") was made long ago, the latter commit 9f49f6dd04 ("gpio: pca953x:
add onsemi,pca9654 id") made use of another, undocumented vendor prefix.
Since such prefix doesn't seem to be used in any device trees, I think we
can just fix the "compatible" string in the driver and the bindings and be
done with that...

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.

TI PCA9536 is 4-Bit I2C GPIO expander without interrupt support[1].
Add support for the same.

Add onsemi,pca9654 which is also compatible with the nxp,pca9524 as it
is an 8bit expander with an interrupt output.

The TCA9539 is almost identical to the PCA9555 and software-compatible
with this driver. It exposes 16 general purpose I/O pins in two 8-bit
configurations.
