Rework the peripheral address to match the updated semantics of
ad_cpu_interconnect, which expects that the addresses are in the range of
0x00010000 - 0x001fffff. This includes updating the base addresses as well
as compressing the used address range to fit into the 2Mb window.

Currently the TX lane mapping is implemented by having to connect tx_phy_s_* to
the tx_ip_s_* and the tx_phy_d_* to the tx_ip_d_* signals in the system
qsys file in the desired order.
Re-work things so that instead the lane mapping is provided through the
TX_LANE_MAP parameter. The parameter specifies in which order logical lanes
are mapped onto the physical lanes.
The appropriate connections are than made inside the core according to this
parameter rather than having to manually connect the signals externally.
In order to generate a 1-to-1 mapping the TX_LANE_MAP parameter can be left
empty.
This change slightly reduces the boiler-plate code that is necessary to
setup the transceiver.

The PLL frequency must be half of the lane rate and the core clock rate
must be lane rate divided by 40. There is no other option, otherwise things
wont work.
Instead of having to manually specify PLL and core clock frequency derive
them in the transceiver script. This reduces the risk of accidental
misconfiguration.

Use the sys_dma_clk clock module for clock and reset signals of the data
path, rather than using the A10GX specific sys_ddr3_cntrl signals. This
enables compatibility for all Altera/Intel platforms.
