net: eth: altera: Resolve false errors from MSGDMA to TSE

This patch resolves false errors from MSGDMA in TX mSGDMA MM to ST
mode, and is a continuation of the patch recently submitted by Andrea
Oetken. The MSGDMA had a logic bug that masked detection of this issue
prior to Quartus 14.1/Build 164. When the MSGDMA logic bug was addressed
in Quartus 14.1/Build 164, the driver problem was exposed.

The problem is corrected by making sure MSGDMA_DESC_CTL_TR_ERR_IRQ is not
set for any of the transmit DMA descriptors, and only used for receive
descriptors.

altera tse: Error-Bit on tx-avalon-stream always set.

The Error-Bit on the avalon streaming interface of the
tx-dma-channel was always set. In SGMII configurations
this leads to error-symbols on the PCS and packet-rejection
on the receiver side (e.g. SGMII/1000Base-X connected switch).

This only applies to the tse-configuration with MSGDMA.

This issue was detected and fixed on a custom board with
a direct connection to a Marvell switch in SGMII-PHY-Mode.
(incl. custom patches for SGMII-PCS).

According to the datasheet if ff_tx_err (avalon-streaming)
is set it is forwarded to gm_tx_err. As a result the PCS
is forwarding the error by sending a "/V/"-caracter.

Altera TSE: Fix sparse errors and warnings

This patch fixes the many sparse errors and warnings contained in the
initial submission of the Altera Triple Speed Ethernet driver, and a
few minor cppcheck warnings. Changes are tested on ARM and NIOS2
example designs, and compile tested against multiple architectures.
Typical issues addressed were as follows:

altera_tse_ethtool.c:136:19: warning: incorrect type in argument
1 (different address spaces)
altera_tse_ethtool.c:136:19: expected void const volatile
[noderef] <asn:2>*addr
