Christopher Haster 9e03b24120 littlefs: Fixed lookahead overflow and removed unbounded lookahead pointers 
As pointed out by davidefer, the lookahead pointer modular arithmetic
does not work around integer overflow when the pointer size is not a
multiple of the block count.

To avoid overflow problems, the easy solution is to stop trying to
work around integer overflows and keep the lookahead offset inside the
block device. To make this work, the ack was modified into a resetable
counter that is decremented every block allocation.

As a plus, quite a bit of the allocation logic ended up simplified.

Christopher Haster 47bee2343c littlefs: Fixed issue with lookahead trusting old lookahead blocks 
One of the big simplifications in littlefs's implementation is the
complete lack of tracking free blocks, allowing operations to simply
drop blocks that are no longer in use.

However, this means the lookahead buffer can easily contain outdated
blocks that were previously deleted. This is usually fine, as littlefs
will rescan the storage if it can't find a free block in the lookahead
buffer, but after changes that caused littlefs to more conservatively
respect the alloc acks (e611cf5), any scanned blocks after an ack would
be incorrectly trusted.

The fix is to eagerly scan ahead in the lookahead when we allocate so
that alloc acks are better able to discredit old lookahead blocks. Since
usually alloc acks are tightly coupled to allocations of one or two blocks,
this allows littlefs to properly rescan every set of allocations.

This may still be a concern if there is a long series of worn out
blocks, but in the worst case littlefs will conservatively avoid using
blocks it's not sure about.

Kari Haapalehto f2b37b7d42 Add new target MTB_ADV_WISE_1530. 
MTB_ADV_WISE_1530 and MTB_USI_WM_BN_BM_22 includes same usi chip,
so common USI_WM_BN_BM_22 target has been created.
MTB_ADV_WISE_1530 and MTB_USI_WM_BN_BM_22 are inheting the common usi target

Andreas Rebert 01d06a9f51 LPC4088: Fix hardfault occuring after power-cycle 
Since revision 5499db1 (mbed-os-5.6.0) a hardfault occurs after a power-cycle.
It doesn't occur after a reset when the application has been downloaded using
drag-and-drop or via debugger. This is probably the reason why this problem
isn't detected when testing new mbed releases.

The hardfault occured in hal_sleep(). Adding a __NOP after __WFI solves the
problem although I don't fully understand why.

- Revision ca661f9 is the last revision where the problem doesn't occur.
- The problem doesn't occur when compiling with GCC instead of ARM compiler
- This issue describes a similar, but not identical problem and led me to test adding a __NOP: https://github.com/ARMmbed/mbed-os/issues/5065
