Matthias Welwarsky dd60dd84f2 icepick-d: extend access to core control register

The ICEPick-D jtag router has core control registers
that provide the same (or similar) functionality as 
the tap control register, for individual cores 
accessible through the same tap (e.g. through a DAP). 

Core control registers are located at address "0x60 + 
core-id" of the ROUTER address space (IR=ROUTER).

It is sometimes helpful or even necessary to modify the
core control register. This patch renames the
"icepick_d_coreid" function to the more appropriate
"icepick_d_core_control" and adds a "value" argument
that allows writing of arbitrary value. 
"icepick_d_tapenable" is extended by an optional value
argument so that core control can be written as the tap
is enabled.
