The DC filter implementation in library/common/dc_filter.v is Xilinx
specific as it uses the Xilinx DSP48 hard-macro. There is a matching Altera
specific implementation in library/altera/common/dc_filter.v.
Move the Xilinx specific implementation from the generic common folder to
the Xilinx specific common folder in library/xilinx/common/ since that is
where all other Xilinx specific common modules reside.

The ad_pps_receiver is instantiated at the top of core.
The rcounter is placed into adc/dac_common registers space, at the
address 0x30 (word aligned).
The interrupt mask is placed into adc/dac_common, at the address 0x04
(word aligned). Because the core has an instance of both modules, the
interrupt masks are OR-ed together.
+ Define two control signal for util_tdd_sync : tdd_sync_en and tdd_terminal_type
+ Delete to old ad_tdd_sync.v instances from the core
+ Update Make files
+ Update ad_tdd_control: add additional CDC logic for tdd_sync (the sync comes from another clock domain)
+ Update the ad_tdd_sync module: it's just a simple pulse generator, the pulse period is defined using a parameter, pulse width is fixed: 128 x clock cycle
+ Update TDD regmap: tdd sync period is no longer software defined
Add .gitattributes file which sets up the eol encoding handling. This will
make sure that we get a uniform eol encoding across different operating
systems.

+ Delete unnecessary registers
+ Add the module ad_addsub.v to resolve additions and subtractions inside TDD control
+ Redefine the burst logic
+ Redesign the control signal generations
+ Note: This patch fix the TDD related timing violations
