pc-bios/s390-ccw: Generate and include dependency files in the Makefile
The Makefile of the s390-ccw bios does not handle dependencies of the
*.c files from the headers yet, so that you often have to run a "make
clean" to get the build right when one of the headers has been changed.
Let's make sure that we generate and include dependency files for all
*.c files now to avoid this problem in the future.

Here's my final pull request for the qemu-5.0 soft freeze. Sorry this
is just under the wire - I hit some last minute problems that took a
while to fix up and retest.
Highlights are:
* Numerous fixes for the FWNMI feature
* A handful of cleanups to the device tree construction code
* Numerous fixes for the spapr-vscsi device
* A number of fixes and cleanups for real mode (MMU off) softmmu
handling
* Fixes for handling of the PAPR RMA
* Better handling of hotplug/unplug events during boot
* Assorted other fixes

Although the real world SiFive HiFive Unleashed board is a 64-bit
hardware configuration, with QEMU it is possible to test 32-bit
configuration with the same hardware features.
This updates the roms Makefile to add the build rules for creating
the 32-bit OpenSBI firmware image for sifive_u machine. A pre-built
OpenSBI v0.6 image has been added as the default bios for 32-bit
sifive_u machine.

misc: Replace zero-length arrays with flexible array member (automatic)
Description copied from Linux kernel commit from Gustavo A. R. Silva
(see [3]):
--v-- description start --v--
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to
declare variable-length types such as these ones is a flexible
array member [1], introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler
warning in case the flexible array does not occur last in the
structure, which will help us prevent some kind of undefined
behavior bugs from being unadvertenly introduced [2] to the
Linux codebase from now on.
--^-- description end --^--
Do the similar housekeeping in the QEMU codebase (which uses
C99 since commit 7be41675f7cb).
All these instances of code were found with the help of the
following Coccinelle script:
@@
identifier s, m, a;
type t, T;
@@
struct s {
...
t m;
- T a[0];
+ T a[];
};
@@
identifier s, m, a;
