Replace 1-element array in drivers/acpi/acpica/amlresrc.h

[PauloMigAlmeida]

Replace one-element array with flexible-array member:

259 struct aml_resource_extended_irq {
260         AML_RESOURCE_LARGE_HEADER_COMMON u8 flags;
261         u8 interrupt_count;
262         u32 interrupts[1];
263         /* res_source_index, res_source optional fields follow */
264 };
265

This header file seems to be generated by a script that lives outside of the Linux kernel code base so according to this chat on the LKML, if one wants to change anything, it should be done on the ACPICA repository instead

There are some related conversations going on here:

• Build fails on "master" with "error: flexible array member 'OemData' not allowed in otherwise empty struct" acpica/acpica#812
• Replace fake flexible arrays with actual flexible array members acpica/acpica#813

As @kees has already opened a PR to fix this and other stuff, I will keep this open (in case I can be of any help).
