milek7 6f1b41351e acpi: Fix ACPI_FLEX_ARRAY in acgcc.h 
acgcc.h defines ACPI_FLEX_ARRAY as struct containing empty struct
and flexible array member. This leads to unintended consequences when
it is compiled as C++ code, because empty struct in C++ is not zero-sized.
This breaks querying interrupt numbers in acpi_irq_routing_table.cpp.
Apply fix from upstream: https://github.com/acpica/acpica/commit/bce7c55e99a0b0db22542c2ed0aeff5571d597cb
