Subject: [PATCH net-next 3/9 v3] ptp: ixp46x: move adjacent to ethernet driver

From: Arnd Bergmann <arnd@...db.de>

The ixp46x ptp driver has a somewhat unusual setup, where the ptp
driver and the ethernet driver are in different directories but
access the same registers that are defined a platform specific
header file.

Moving everything into drivers/net/ makes it look more like most
other ptp drivers and allows compile-testing this driver on
other targets.

ChanegLog v2->v3:
- Rebased on v5.5-rc1
ChangeLog v1->v2:
- Rename patch as "move ADJACENT" which makes more sense
