[PATCH 3/3] net: macb: fix compiler warning for 64 bit systems

[Michael Tretter]

On arm64 the compiler prints the following warning, when the macb driver
is enabled:

	warning: cast from pointer to integer of different size

Add the same explicit cast as implemented for all other dma addresses in
the macb driver.

Fixes: befd110b5922 ("net: macb: init multiple dummy TX queues")
