This is a pure rename without any changes. It makes maintaining bgmac simpler and will hopefully make adding new kernel a bit easier. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH] bgmac: add helper checking for BCM4707 / BCM53018 chip id

Chipsets with BCM4707 / BCM53018 ID require special handling at a few
|
|
places in the code. It's likely there will be more IDs to check in the
|
|
future. To simplify it add this trivial helper.
