[ Upstream commit 5886b130de953cfb8826f7771ec8640a79934a7f ]
via_core_init() won't exit the driver when pci_register_driver() failed.
Exit the viafb-i2c and the viafb-gpio in failed path to prevent error.
VIA Graphics Integration Chipset framebuffer 2.4 initializing
Error: Driver 'viafb-i2c' is already registered, aborting...
Error: Driver 'viafb-gpio' is already registered, aborting...
Fixes: 7582eb9be85f ("viafb: Turn GPIO and i2c into proper platform devices")
