Not every arch has io memory.
So, unbreak the build by fixing the dependencies.

The nps_enet driver happily mixes virtual, physical and __iomem
addresses, which are all different depending on the architecture
and configuration. That causes a warning when building the code
on ARM with LPAE mode enabled:
drivers/net/ethernet/ezchip/nps_enet.c: In function 'nps_enet_send_frame':
drivers/net/ethernet/ezchip/nps_enet.c:370:13: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
but will also fail to work for other reasons.
In this patch, I'm trying to change the code to use only normal
kernel pointers, which I assume is what the author actually meant:
* For reading or writing a 32-bit word that may be unaligned when
an SKB contains unaligned data, I'm using get_unaligned/put_unaligned()
rather than memcpy_fromio/toio.
* For converting a u8 pointer to a u32 pointer, I use a cast rather
than the incorrect virt_to_phys.
* For copying a couple of bytes from one place to another while respecting
alignment, I use memcpy instead of memcpy_toio.

We define buf_int_enable in the minimal namespace it is used.

This is needed for when TX done interrupt is in
"level mode".
For example it is true for some simulators of this device.

We set controller to drop control frames and not trying
to pass them on. This is only needed for debug reasons.

We need to set tx_skb pointer before send frame.
If we receive interrupt before we set pointer we will try
to free SKB with wrong pointer.
Now we are sure that SKB pointer will never be NULL during
handling TX done and check is removed.

When interrupt is received we read directly from control
register for RX/TX instead of reading cause register
since this register fails to indicate TX done when
TX interrupt is "edge mode".

Simple LAN device for debug or management purposes.
Device supports interrupts for RX and TX(completion).
Device does not have DMA ability.
