While most platforms implement LED banks in sets of 8/16/32, some use
different configurations. This adds a LED mask to the heartbeat platform
data to allow platforms to constrain the bitmap, which is otherwise
derived from the register size.

Add some flags for the heartbeat driver, and kill off some duplication
in the bit positions for the boards that don't have special cases.
This also allows for variable access widths and inversion.

This implements stricter and more compliant knightrider strobing in the
heartbeat handler. While there still seems to be some debate as to
whether the double 0 is "more" correct or not, this updated version
appears to have general consensus. Fixes a long-term "bug".
