This allows to share some common code for the boards that use a corenet
base SoC.
Two different versions of the function are available in
fsl_corenet_serdes.c and fsl_corenet2_serdes.c files.

Since the parameters need to be modified according to different Serdes
protocols at runtime, the const will block this. Also remove const from
arrays define used by vsc3316_config.

Add emulator support for T4240. Emulator has limited peripherals and
interfaces. Difference between emulator and T4240QDS includes:
ECC for DDR is disabled due the procedure to load images
No board FPGA (QIXIS)
NOR flash has 32-bit port for higher loading speed
IFC and I2C timing don't really matter, so set them fast
No ethernet

Use QIXIS measurement registers to obtain sysclk and ddr clock. This
allows using non-standard clock speeds, set by directly writing to
clock chip or store the values in qixis clock data eeprom.

Allow VDD voltage overriding with a command. This is an add-on feasture of
VID. To override VDD, use command vdd_override with the value of voltage
in mV, for example
vdd_override <voltage in mV, eg. 1050>
The above example will set the VDD to 1.050 volt. Any wrong value out of
range of 0.8188 to 1.2125 volt or invalid string is ignored.
In addition to the command, if overriding VDD is needed earlier in booting
process, save an variable and reboot:
setenv t4240qds_vdd_mv <voltage in mV>
saveenv

Static variables should be defined in C files, not header files, because
otherwise every C file that #includes the header file will generate a
duplicate of the variables. Since the vsc3316_xxx[] arrays are only
used by t4qds.c anyway, just put the variables there.

The T4240QDS is a high-performance computing evaluation, development and
test platform supporting the T4240 QorIQ Power Architecture™ processor.
SERDES Connections
32 lanes grouped into four 8-lane banks
Two “front side” banks dedicated to Ethernet
Two “back side” banks dedicated to other protocols
DDR Controllers
Three independant 64-bit DDR3 controllers
Supports rates up to 2133 MHz data-rate
Supports two DDR3/DDR3LP UDIMM/RDIMMs per controller
QIXIS System Logic FPGA
Each DDR controller has two DIMM slots. The first slot of each controller
has up to 4 chip selects to support single-, dual- and quad-rank DIMMs.
The second slot has only 2 chip selects to support single- and dual-rank
DIMMs. At any given time, up to total 4 chip selects can be used.
Detail information can be found in doc/README.t4qds
