This change doesn't do what the above changelog says.  It introduces a
new struct reg_sequence and updates the multi write and patch APIs to
use that but it doesn't implement any delay functionality.  Please
resend with a clearer changelog that describes why the struct is being
split out from the reg_defaults struct and makes it clear that this is
just a rename.  It's probably best to also defer the addition of the
delay field until the second patch where this function is actually
implemented.

No blank line between the kerneldoc and the struct (as is the style for
other kernel code).
