staging: mt7621-pci: remove 'offset' with mem and io resource sizes

Browse Source 
Offset contains resources size for both io and memory resources.
Those fields are directly initialized to zero and set up using
'pci_add_resource_offset' function. Instead of doing that remove
them and use directly function 'pci_add_resource' where zero is
passed directly to its internal call to 'pci_add_resource_offset'.
