An option is provided to avoid using SDL in U-Boot sandbox (and drop

When a command is passed into sandbox using the '-c' argument the
command is run directly. This is most helpful when running tests (such
as test-dm.sh). Previously the exit code was an unused enum. Change it
to be the actual return code from the command so that the script calling
sandbox can know if the command succeeded (tests passed).  Also remove
the now completely unused "exit_state" in sandbox.

Since we have src, div and pre-div mask bits defined corresponding
to peripherals, calculation of clock specific to I2C appears
redundant and confusing. Using clk_bit_info struct we can write
calculations generic to all peripherals which makes code easy to
understand and free from peripheral specific exceptions.

ARC HS and ARC EM are new cores based on ARCv2 ISA which is binary
incompatible with ISAv1 (AKA ARCompact).

Significant difference between ISAv2 and v1 is implementation of
interrupt vector table.

In v1 it is implemented in the same way as on many other architectures -
as a special location where user may put whether code executed in place
(if machine word of space is enough) or jump to a full-scale interrupt
handler.

In v2 interrupt table is just an array of adresses of real interrupt
handlers. That requires a separate section for IVT that is not encoded
as code by assembler.

This change adds support for following cores:
 * ARC EM6 (simple 32-bit microcontroller without MMU)
 * ARC HS36 (advanced 32-bit microcontroller without MMU)
 * ARC HS38 (advanced 32-bit microcontroller with MMU)

As a part of ARC HS38 new version of MMU (v4) was introduced.

Also this change adds AXS131 board which is the same DW ARC SDP base board but
with ARC HS38 CPU tile.
