Moving the of_net code from drivers/of/ to net/core means we
no longer stub out the helpers when networking is disabled,
which leads to a randconfig build failure with at least one
ARM platform that calls this from non-networking code:
arm-linux-gnueabi-ld: arch/arm/mach-mvebu/kirkwood.o: in function `kirkwood_dt_eth_fixup':
kirkwood.c:(.init.text+0x54): undefined reference to `of_get_mac_address'
Restore the way this worked before by changing that #ifdef
check back to testing for both CONFIG_OF and CONFIG_NET.

random_ether_addr() was the original name of the helper which
was kept for backward compatibility (?) after the rename in
commit 0a4dd594982a ("etherdevice: Rename random_ether_addr
to eth_random_addr").
We have a single random_ether_addr() caller left in tree
while there are 70 callers of eth_random_addr().
Time to drop this define.

Some of the changes here are not strictly required - const

It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled

Expose SMA and U.FL connectors as ptp_pins on E810-T based adapters and
allow controlling them.
E810-T adapters are equipped with:
- 2 external bidirectional SMA connectors
- 1 internal TX U.FL
- 1 internal RX U.FL
U.FL connectors share signal lines with the SMA connectors. The TX U.FL1
share the line with the SMA1 and the RX U.FL2 share line with the SMA2.
This dependence is controlled by the ice_verify_pin_e810t.
Additionally add support for the E810-T-based devices which don't use the
SMA/U.FL controller. If the IO expander is not detected don't expose pins
and use 2 predefined 1PPS input and output pins.

The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are

The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal
TCP/IP Offload Engine (TOE) and Dedicated Direct memory access controller
(DMAC).
With a few changes in the driver we can support both IPs.
This patch series is aims to add functional support for Gigabit Ethernet
