if_mvneta: Use clock frequency

Make neta use frequency obtained from clock, instead of
hardcoded one. Use default frequency in case of clock
device failure. Remove unnecessary function calls
to obtain frequency and use cached one instead.

mvneta: Fix 64-bit MIB reads

It appears we must read MIB values as 2 4-byte words, lower address
first. A single 8-byte MIB read returns the value with the lower 4
bytes copied into the upper 4 bytes, resulting in bogus byte counter
values.

Implement jumbo frame support in mvneta driver

This patch introduces processing of the frames
up to 9kB by the mvneta driver. Some versions of
this NIC limit TX checksum offloading, depending
on the frame size, so add appropriate handling
of this feature.

Store virtual address of buffer in mvneta_rx_ring

Now the virtual address of received buffer is taken from a software ring.
Thanks to this, we can use the NETA driver on 64 bits architecture and
avoid 32-bit buf_cookie descriptor field limitation.

Introduce Armada 38x/XP network controller support

This patch contains a new driver for the network unit of Marvell
Armada 38x/XP SoCs, called NETA. This support was thoroughly tested
and optimised in terms of stability and performance. Additional
hardware features, like Buffer Management (BM) or Parser and Classifier
(PnC) will be progressively supported as needed.
