[DRIVER] pca953x: support reset-gpios shared line

Some systems connect several devices to a single reset GPIO. For these devices to get out of reset and probe successfully, treat the reset returning -EBUSY as the line already having been hogged and do not abort the probe.

[DRIVER] fxl6408: add reset-gpios control with shared line support

Add optional reset-gpios pin control. Also, some systems connect several devices to a single reset GPIO. For these devices to get out of reset and probe successfully, treat the reset returning -EBUSY as the line already having been hogged and do not abort the probe.
