Turns out the documentation is wrong and doing "RAISE 1" does not result
in a software reset, only a core reset.  So when the on-chip rom has a
functioning reset helper, use it.

Since the value of these MMRs aren't changing, store the value in a local

The BF537 SIC combines the gpio port H mask A interrupts with the
emac rx interrupt, so we need to demux this in software.

It also combines the gpio port H mask B and the emac tx interrupts,
and the watchdog and port F mask B interrupts, but since we don't
support mask B yet, just add the defines for now.

The search logic in the gpio demux walks all possible gpio blocks starting
at the specified pin.  The trouble on bf537 parts when we demux the port
F and port G mask A interrupts is that we also demux port H mask A ints.
Most of the time this isn't an issue as people don't usually use port H,
but might as well avoid it when possible.

This functionality was merged into the common bfin_pm_standby_ctrl func
some time ago, so punt these now unused funcs and data, and localize the
wake funcs that aren't needed externally anymore.

The SIC interrupt line muxing that the bf537 does is specific to this
CPU (thankfully), so rip it out of the common code and move it to a
bf537-specific file.  This tidies up the common code significantly.

After some cache setup reordering changesets, the blackfin_cpudata init
was left behind.  While cpu0's data was correct, cpu1's data was not.
Not that big of a deal as these are only used in the cpuinfo output, but
should still be fixed.  So move the setup of these fields to the common
cache setup function to avoid this happening again in the future.
