Add MAINTAINERS entries for new scx200_hrt and pc8736x_gpio drivers, and
take over maintenance of scx200_gpio, authored by Christer Weinigel (which
I've hacked at), who no longer has the hardware.

Also take over hwmon/pc87360, authored by Jean Delvare, who's dropped
maintenance to dedicate more time to hwmon subsystem.
