staging: greybus: Replace zero-length array by DECLARE_FLEX_ARRAY() helper

The code currently uses C90 standard extension based zero length array
struct which is now deprecated and the new C99 standard extension of
flexible array declarations are to be used instead. Also, the macro
DECLARE_FLEX_ARRAY() allows to use single flexible array member in a
structure. Refer to these links [1], [2], and [3] for details.
