board: arc: hsdk_2cores: Re-add missing taps into JTAG chain

Browse source 
On introduction of a "simplified" HSDK configuration where we only
use 2 cores out of 4 (in assumption that it will be working much
more reliably) we excluded a bit too much of details from OpenOCD script.

In particular we stripped not-used cores from JTAG chain description
which made OpenOCD quite unhappy:
----------------------------->8----------------------------
Info : ftdi: if you experience problems at higher adapter clocks, try the command "ftdi_tdo_sample_edge falling"
Info : clock speed 10000 kHz

That lead us to the situation when the target cores were programmed
in a wrong way effectively failing all tests. Fixing it now.
