[PATCH net-next 3/4] net: renesas: rswitch: Remove gptp flag from rswitch_gwca_queue

[Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx>]

The gptp flag is completely related to the !dir_tx in struct
rswitch_gwca_queue. In the future, a new queue handling for
timestamp will be implemented and this gptp flag is confusable.
So, remove the gptp flag.
