The bulk of the patch comes from the __iomem changes.
- the phy read and write operations were carrying the chip id deep
down the call chain. Let's waste a pointer and contain the flying
spaghetti monster.
- phy_{read, write}_1bit only need to access the DCR9 register. The loss
of generality here should not hurt.
- removed a leftover printk of the EISA era. This is a pure PCI device.

The eeprom registers always use the same PCI bar whereas the general
registers may either use the same mapping as the eeprom registers or
a different one. It is thus possible to simplify parse_eeprom().

Since vlan egress map is only good for tagged traffic, need to have other
mapping to be used by untagged traffic.
For that, the driver uses sch_mqprio mapping. This mapping could be set by
using tc tool from iproute2 package.
Mapped UP will be used by the HW for QoS purposes, but won't go out on the
wire.

Instead of relying on HW to change schedule queue by UP, schedule
queue is fixed for a tx_ring, and UP in WQE is ignored in this aspect. This
resolves two issues with untagged traffic:
1. untagged traffic has no UP in packet which is needed for QoS. The change
above allows setting the schedule queue (and by that the UP) of such a stream.
2. BlueFlame uses the same field used by vlan tag. So forcing UP from QPC
allows using BF for untagged but prioritized traffic.
In old firmware that force UP is not supported, untagged traffic will not subject to
QoS.
Because UP is set by QP, need to always have a tx ring per UP, even if pfcrx
module paramter is false.

If a specific clk_csr value is passed from the platform
this means that the CSR Clock Range selection cannot be
changed at run-time and it is fixed (as reported in the driver
documentation). Viceversa the driver will try to set the MDC
clock dynamically according to the actual clock input.

The CSR Clock Range has been reworked and new macros has
been added in the platform header to allow the CSR Clock
Range selection in the GMII Address Register.
The previous work didn't add the other fields
that can be used to achieve MDC clock of frequency
higher than the IEEE 802.3 specified frequency limit
of 2.5 MHz and program a clock divider of lower value.
On such platforms, these are used indeed so this patch
adds them.

This patch re-works the internal GMAC DMA parameters
passed from the platform.
In the past, we only passed the pbl but, with new core,
other parameters can be passed and are mandatory on some
platforms.
New parameters are documented in stmmac.txt because this
patch has an impact for many platforms.

This patch sanities the RX coe and adds the Type-1 Rx checksum offload engine (COE).
So the RX COE can be passed through the platform but can be fixed
at run-time in case of the core has the HW capability register.
Also to support the Type-1 Rx COE the driver must append the
HW checksum at the end of payload in case the Rx checksum
engine was used to offload the HW checksum.
This v2 version also fixes the IPC that has to be enabled and verified.
