arm64, configs: SMMUv2: Separate stream ID's mask and id
The SMMUv2 allows filtering bits when matching stream IDs before they're
passed to the TCU. In this way multiple streams legally get the same
translation.
On boards such as the ZCU Ultrascale+, the master ID needed to identify
the corresponding SMMU stream ID may be dependent on a specific AXI ID
that is set by the PL (and could be IP specific).
One single fixed mask to pass to the SMR to compact multiple stream IDs
before they "hit" the TCU is not flexible enough. The use-case is to
compact similar PL-originating masters and have the SMMU behaving the
same for them (e.g., they're assigned to the same inmate). At the
same time, one needs a full stream_id to assign e.g., different GEM
ethernets to different inmates.
Update a stream_id to support two different interpretations:
- for the SMMUv2, provide an explicit mask_out + ID.
- for the SMMUv3, keep the current single ID.
This commit updates the SMMUv2 / v3 --including configuration--
accordingly.

configs: add Wall and fix bracketing
In combination with Wextra, Wall enables additional checks such as
Wmissing-braces.

configs, inmates: Makefile: remove .note.gnu.property section during objcopy
It seems that the .note.gnu.property section is interfering with objcpy and
causes the "JHSYST" identification to be removed from the .cell.
Removing the section while copying the .o fixes the issue:
objcopy --version
GNU objcopy (GNU Binutils for Ubuntu) 2.34
readelf -a jailhouse/configs/x86/qemu-x86.o
