[PATCH] firmware: arm_scmi: Replace zero-length array with flexible-array member

[cgel.zte at gmail.com]

From: Lv Ruyi <lv.ruyi at zte.com.cn>

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
