[PATCH 1/2] net: bcmgenet: fix warning when building for 32-bit

[Ahmad Fatoum]

The driver readily works in 32-bit mode as it takes care there
to write zero to the DMA_DESC_ADDRESS_HI field of descriptors.
In the receive path, a 32-bit integer is shifted by 32 though
leading to a (harmless) warning. Adjust the type to silence it.
