net: phy: aquantia: use generic firmware loader

Browse Source 
Aquantia PHYs are being used w/o SPI flash in some routers recently.
Current firmware loader only attempts to load from FS on top of MMC,
limiting the use on many devices.

Removed the old firmware loader, migrate to generic script based firmware
loader to allow a wider range and runtime override of firmware source.
(e.g., MMC, USB, UBIFS).

Tested on Buffalo WXR18000BE10P with UBIFS.

Aquantia PHYs use firmware which can be either loaded automatically
from storage directly attached to the phy or loaded by the boot loader
via MDIO commands. The firmware is loaded from a file, specified by
the PHY_AQUANTIA_FW_PART and PHY_AQUANTIA_FW_NAME options.
