These functions are used by code outside the network support, so move them
to lib/ to be more accessible.

Without this, the functions are only accessible in SPL/TPL only if
CONFIG_SPL/TPL_NET are defined. Many boards do not enable those option but
still want to do checksums in this format.

Commit b618b370 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig")
accidentally set the default *option* TFTP block size to 512 bytes, even
though the comment in the code says that this is a terrible choice. Most
boards didn't define the symbol before, so they got the default block size
of 1468 bytes before, but now use 512 bytes, which is also the fallback.
This leads to both abysmal performance and a lot of hashes printed
on the screen (one character for every 5K), which is both annoying and
slow over serial links.

Set the default block size in Kconfig back to the value it had before.

This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.

device_probe() may fail in which case the seq_id will be -1. Don't
display these devices during startup. While this is only a cosmetic
change, the return value of eth_initialize() will also change to the
actual number of available devices. The return value is only used in
spl_net to decide whether there are any devices to boot from. So
returning only available devices is also more correct in that case.

During testing of qemu-riscv32 with a 2GiB memory configuration,
tftp always fails with a error message:

  Load address: 0x84000000
  Loading: #
  TFTP error: trying to overwrite reserved memory...

It turns out the result of 'tftp_load_addr + tftp_load_size' just
overflows (0x100000000) and the test logic in store_block() fails.
Fix this by adjusting the end address to ULONG_MAX when overflow
is detected.

rpc_pkt.u.call.data is an array of uint32_t. There is no need to convert
it to uint32_t *.

memcpy() expects void * as it 1st and 2nd argument. There is no point in
converting pointers to char * before passing them to memcpy().

In ntohl(data[1]) != 0 calling ntohl() is superfluous. If the value is
zero, does not depend on the byte order.

Use the optional property device-name to name the MDIO bus.  This works
around limitations with using the DT node name on devices such as
Armada-8040, which integrates two cp100 cores, both featuring MDIOs at the
same relative offsets and with the same DT node names.
The concept was originally proposed by Marvell as a custom property called
mdio-name specific to Marvell driver.  This patch uses the more generic
property device-name and moves this into MDIO class code so other can use
it as well.
