[PATCH net-next] net: axienet: Fix coding style issues

[Radhey Shyam Pandey]

From: Appana Durga Kedareswara Rao <appana.durga.rao@xilinx.com>

Replace all occurences of (1<<x) by BIT(x) to get rid of checkpatch.pl
"CHECK" output "Prefer using the BIT macro".

It also removes unnecessary ftrace-like logging, add missing blank line
after declaration and remove unnecessary parentheses around 'ndev->mtu
<= XAE_JUMBO_MTU' and 'ndev->mtu > XAE_MTU'.

Ideally, this should of been multiple patches. In general, we want a
patch to do one thing, which makes it easier to review.

net-next is closed at the moment due to the merge window. Please
repost in two weeks, once it opens again.

FWIW the BIT() thing is a matter of preference, we don't enforce it
strictly in networking, it may not be worth patching. Up to you.

## Form letter - net-next-closed

The merge window for v6.11 and therefore net-next is closed for new
drivers, features, code refactoring and optimizations. We are currently
accepting bug fixes only.

Please repost when net-next reopens after July 29th.

RFC patches sent for review only are obviously welcome at any time.

In the past, I recall we did.
