[PATCH net-next] sfc: mark some unexported symbols as static

[Edward Cree]

From: kbuild test robot <fengguang.wu@xxxxxxxxx>

efx_default_channel_want_txqs() is only used in efx.c, while
 efx_ptp_want_txqs() and efx_ptp_channel_type (a struct) are only used
 in ptp.c.  In all cases these symbols should be static.

Fixes: 2935e3c38228 ("sfc: on 8000 series use TX queues for TX timestamps")
