[XEN PATCH] docs/misra: document the usage of array range initializers

[Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx>]

The usage of a documented GNU extension that allows a range of elements
in an array to be initalized to the same value using a designated
initalizer is added to this document, to fully comply with
MISRA C:2012 Rule 1.1.
