[PATCH v4 05/30] lib: Fix style for acpi.{c,h}

[Nikos Nikoleris <nikos.nikoleris@xxxxxxx>]

Manually fix style issues to make the files consistent with the kernel
coding style.

Zero-length array members have been replaced with flexible array members
(for details about the motivation, consult
Documentation/process/deprecated.rst in the Linux tree, the section about
zero-length and one-element arrays).
