Subject: [PATCH] fbdev/amifb: Replace zero-length arrays with DECLARE_FLEX_ARRAY() helper

Replacing zero-length arrays with C99 flexible-array members
because they are deprecated. Use the new DECLARE_FLEX_ARRAY()
auxiliary macro instead of defining a zero-length array.

This fixes warnings such as:
./drivers/video/fbdev/amifb.c:690:6-10: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
