While sandbox works OK without the special-case code, it does result in
console output being stored in the pre-console buffer while sandbox starts
up. If there is a crash or a problem then there is no indication of what
is going on.

For ease of debugging it seems better to revert this change also.

The .probe_chip function is supposed to probe an i2c device on the bus to
determine whether a device is answering to a particular address.
at91_i2c_probe_chip() did not do anything resembling this and always
returned 0.

It looks as though at91_i2c_probe_chip() was intended to be a .probe
function for the controller, as it was copied-and-pasted to become
at91_i2c_probe() in 0bc8f640.

Removing the at91_i2c_probe_chip() function makes the higher layer
(i2c_probe_chip()) try a zero-length read transfer to test for the
presence of a device instead, which does work.

The driver must wait for TXRDY after each byte is pushed into
the i2c FIFO before pushing the next byte. Previously this was
not done for the first byte, causing a race condition with zeros

1. To get OBJ token, pair of create and open API replaces create APIs
2. Pair of close and destroy APIs replaces destroy APIs
3. For version read, get_version APIs replaces get_attributes APIs
4. dpni_get/reset_statistics APIs replaces dpni_get/set_counter APIs
5. Simplifies struct dpni_cfg and removes dpni_extended_cfg struct
6. Single API dpni_get_buffer_layout/set_buffer_layout replaces

Since commit 2614a208 ("common: command: tempory buffer should
have size of command line buf"), there have been consistent Travis CI
failures on my builds (interestingly not for Tom, even though building
the same commit id) due to a SEGV in building the byteswapped
omapimage:
     	    arm: pcm051_rev3
     make[2]: *** [MLO.byteswap] Error 139
     	      	  		       ^^^ error code for a SEGV

Turns out that the word-based byte-swapping loop in omapimage.c is to
blame. With the loop condition
       while (swapped <= (sbuf->st_size / sizeof(uint32_t)))
there had been one-too-many iterations for all file sizes divisible by
the sizeof(uint32_t).  I.e. we had 1 iteration for 0 bytes (and also 1
through 3 bytes) and 2 iterations at 4 bytes... clearly overshooting
on 0 and 4 bytes.

This commit fixes the calculation of an up-rounded word-count and
makes sure to keep the zero-based loop-counter below the number of
words to be processed.
