Somewhere along recent changes to power control of the wl1835, power-on
became very unreliable on the hikey, failing like this:

As mentioned in the info pages of gas, the '.align' pseudo op's
interpretation of the alignment value is architecture specific.
It might either be a byte value or taken to the power of two.
On ARM it's actually the latter which leads to unnecessary large
alignments of 16 bytes for 32 bit builds or

Hi Linus,
here is the big pull request for pin control changes this merge

It took some days to stabilize some last minute Kconfig changes
and I wanted some build coverage before sending the pull request.
We have no core changes but lots of incremental development

Currently, CONFIG_JUMP_LABEL just means "I _want_ to use jump label".
The jump label is controlled by HAVE_JUMP_LABEL, which is defined
like this:

# define HAVE_JUMP_LABEL
#endif
We can improve this by testing 'asm goto' support i
Set TRACE_INCLUDE_PATH correctly for exceptions.h and irq_vectors.h
This is consistent with fpu.h, hyperv.h, mpx.h in the same directory.
The ugly include paths will go away.
