For Zephyr rtos support it is necessary to define general register
numbers for architecture. There were some already in arc.h file.
Let's define ARC registers numbers as a set instead of separate defines.

Modify the format strings to properly handle uint32_t data types.
While there, fix prototype mismatch between header and C file of
the function armv7a_l1_d_cache_inval_virt().

Actionpoint mechanism allows to setup HW breakpoints and watchpoints on Synopsys ARC CPUs.
This mechanism is controlled by DEBUG register and by a set of auxilary registers.
Each actionpoint is controlled by 3 aux registers: Actionpoint(AP) match mask(AP_AMM),
AP match value(AP_AMV) and AP control(AC).
Note: some fields of actionpoint_t structure will be used in further
support of watchpoints.

With this commit we introduce L1 and L2 cache
flush and invalidate operations which are necessary for
getting/setting actual data during memory r/w operations.
We introduce L2 cache support, which is not presented
on currently support EMSK board. But L2 is presented
on HSDK board, which soon will be introduced.

With this patch we introduce set/unset breakpoints
routines and add/remove bp handlers.
Currently soft breakpoints are only supported.
Changes since v1:
* Change if-statement in arc_remove_breakpoint
* Squash changes from http://openocd.zylin.com/#/c/5641/
in this commit to fix build.

This patch is an initial bump of ARC-specific code
which implements the ARCv2 target(EMSK board) initializing
routine and some basic remote connection/load/continue
functionality.
Changes:
03.12.2019:
-Add return value checks.
-Using static code analizer next fixes were made:
Mem leak in functions:
arc_jtag_read_memory,arc_jtag_read_memory,
arc_jtag_write_registers, arc_jtag_read_registers,
jim_arc_add_reg_type_flags, jim_arc_add_reg_type_struct,
arc_build_reg_cache, arc_mem_read.
Dead code in "arc_mem_read";
In arc_save_context, arc_restore_context correct arguments
in"memset" calls.
In "build_bcr_reg_cache", "arc_build_reg_cache" check
if list is not empty.
29.12.2019
-Moved code from arc_v2.c to arc.c
-Added checks of the result of calloc/malloc calls
-Reworked arc_cmd.c: replaced spagetty code with functions
-Moved to one style in if statements - to "if(!bla)"
-Changed Licence headers
22.01.2020
-Removed unused variables in arc_common
-Renamed register operation functions
-Introduced arc_deinit_target function
-Fixed interrupt handling in halt/resume:
* add irq_state field in arc_common
* fix irq enable/disable calls ( now STATUS32 register is used)
-Switched from buf_set(get)_us32() usage to target_buffer_set(get)_u32()
-Made some cleanup
30.01.2020
-Removed redundant arc_register struct, moved target link to arc_reg_desc
-Introduced link to BCR reg cache in arc_common for freeing memory.
-Now arc_deinit_target frees all arc-related allocated memory.
Valgrind shows no memory leaks.
-Inroduced arch description in arc.c
01.02.2020
-Remove small memory allocations in arc_init_reg. Instead created reg_value
and feature fields in arc_reg_desc.
-Add return value for arc_init_reg() func.
-Replaced some integer constants(61,62,63) with defines.
-Removed redundant conversions in arc_reg_get_field().
-Moved iccm/dccm configuration code from arc_configure()
to separate functions.
19.02.2020
-Change sizeof(struct) to sizeof(*ptr) in allocations
-Changed if/while(ptr != NULL) to if/while(ptr)
-Removed unused variables from struct arc_jtag
-Add additional structs to arc_reg_data_type
to reduce amount of memory allocations calls
and simplifying memory freeing.
-Add helper arc_reg_bitfield_t struct which includes
reg_data_type_bitfield object and char[] name. Reduces
memory allocations calls.
-Add limit for reg_type/reg_type_field names(20 symbols).
-Add in jim_arc_add_reg_type*() functions additional
argnument checks(amount of field/name size).
-In jim_arc_add_reg_type*() reduced amount of memory allocations.
-Cleanup of jim_arc_add_reg_type*() functions.
-For commands update ".usage" fields according docopt.
-Cleanup in arc_jtag.c
-Renamed functions which require jtag_exeutre_queue() to arc_jtag_enque_*()
-Add arc_jtag_enque_register_rw() function, which r/w to jtag ir/dr regs
during regiter r/w.
24.02:
-Change include guards in arc* files according coding style
-Remove _t suffix in struct arc_reg_bitfield_t
-Some cleanup
