After the recent ixp4xx cleanups, the ptp driver has gained a
build failure in some configurations:
drivers/net/ethernet/xscale/ptp_ixp46x.c: In function 'ptp_ixp_init':
drivers/net/ethernet/xscale/ptp_ixp46x.c:290:51: error: 'IXP4XX_TIMESYNC_BASE_VIRT' undeclared (first use in this function)
Avoid the last bit of hardcoded constants from platform headers
by turning the ptp driver bit into a platform driver and passing
the IRQ and MMIO address as resources.
This is a bit tricky:
- The interface between the two drivers is now the new
ixp46x_ptp_find() function, replacing the global
ixp46x_phc_index variable. The call is done as late
as possible, in hwtstamp_set(), to ensure that the
ptp device is fully probed.
- As the ptp driver is now called by the network driver, the
link dependency is reversed, which in turn requires a small
Makefile hack
- The GPIO number is still left hardcoded. This is clearly not
great, but it can be addressed later. Note that commit 98ac0cc270b7
("ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER") changed the
IRQ number to something meaningless. Passing the correct IRQ
in a resource fixes this.
- When the PTP driver is disabled, ethtool .get_ts_info()
now correctly lists only software timestamping regardless
of the hardware.

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.

Add SPDX license identifiers to all Make/Kconfig files which:
- Have no license information of any form
These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:

The platform is removed, so there are no users of this driver.

Move the Intel XScale IXP drivers into drivers/net/ethernet/xscale/
and make the necessary Kconfig and Makefile changes.
