ps3_gelic_wireless: Remove PS3 gelic legacy wpa support

The current PS3 gelic wireless driver has support for wireless
extensions. The original PS3 gelic wireless driver exposed a
dedicated API for a dedicated wpa_supplicant driver. This old
API could be enabled with CONFIG_GELIC_WIRELESS_OLD_PSK_INTERFACE,
however, as this is not being used by any distros, and it is being
removed from the driver and from wpa_supplicant.
