[PATCH 6/6] net: fsl_enetc: fix compilation for 32-bit

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The driver is only used on the 64-bit LS1028, but compile testing on
32-bit fails mostly due to unnecessary pointer casts.

Fixing them cleans up the code a little, so let's do that even if
there's no functional change.
