Update ARC's elfarcv2 script template with:
- The .ivt section (Interrupt Vector Table) is mapped at the begining
of STARTUP_MEMORY when ivtbase_addr is not defined. Previously, it
was pointing to 0x00.
- MEMORY_FILE is a new emulation paramter and sets the name for the
linker script file which holds the MEMORY commands required by
arcv2elfx emulation.
- Four new linker variables are introduced available when arcv2elf emulation is used:
* __TEXT_REGION_ORIGIN__ Once defined it is setting the text region origin. By default it points to zero.
* __TEXT_REGION_LENGTH__ Once defined it is setting the text region length. By default it is set to 2M.
* __DATA_REGION_ORIGIN__ Once defined it is setting the data region origin. By default it is set to 0x80000000.
* __DATA_REGION_LENGTH__ Once defined it is setting the data region length. By default it is set to 2M.

* scripttempl/elfarcv2.sc: Update script template.
