Instead of allowing the client to set a caching attribute
in the io_mem() call of the device interface, which was
only used to decide in between of the memory being
write-combined or not, remove it from the API.
Instead use the information delivered by the devices ROM,
whether memory from a PCI BAR is prefetchable or not,
to decide whether it is mapped write-combined or not.
Ref genodelabs/genode#4578
Memory descriptors in PCI BARs have a prefetchable bit, which can
be used to optimize memory access when setting, e.g. write-combined
in page-table entries.

The DHCP client used to always send packets with a size of 1024 regardless of
the size of the actual content, which was always significantly lower. 1024
bytes was simply a guess to provide enough space for all types of DHCP client
packets. As we know the exact size of each packet the DHCP client sends even
before packet creation, this commit makes use of the knowledge resulting in
much smaller packets sent by the DHCP client.
Fixes#4619
On some Cortex A9 platforms (Qemu 4.2.1 PBXA9), the IRQ status register is not
reliable. Sometimes, it indicates an IRQ too early, i.e., shortly before the
counter wraps. Therefore we have to accomplish wrap detection via counter
comparison only. We check whether the current counter value is higher than the
start counter value of the current timeout.
However, this implies that we have to take care to always read out the counter
before it hits the max timout value again. And, therefore, the max timeout
value has to be far away from the first value the counter has after wrapping.
Consequently, we propagate a max timeout value of half the max counter value.
Fixes#4209
* Remove wrapper for legacy x86 platform API
* Move PCI configuration space quirks to corresponding driver
(pc_usb_host_drv, pc_wifi_drv, pc_intel_fb_drv)
* Adapt driver test run-scripts to changed configuration

Consumes the information about reserved memory region reports from
the devices ROM, and adds appropriated mappings to the corresponding
device PD.
Ref genodelabs/genode#4578
We need the information about reserved memory region reports
from the ACPI tables within the platform driver to pre-fill
IOMMU tables with the corresponding mappings. Therefore,
the pci_decode component now parses the information from the
ACPI ROM, and adds "reserved_memory" nodes to all related
devices in the devices report.

In case of the GPU multiplexer, we need to delegate MMIO memory
to the framebuffer client in form of a managed dataspace. To be
able to attach a given Platform::Device::Mmio object to a region map
we need to access its capability.

This commit fixes two issues with the timeout lib and the base-hw src recipe:
* Add source files of timeout lib to recipe content.
The files weren't copied to the depot until now. However, the archive
nonetheless built successfully because of the second issue that is described
below.
* Get rid of the usage of the BASE_DIR variable in the timeout lib.
The BASE_DIR variable always resolves to the repos/base directory even when
building in a depot. That said, the use of BASE_DIR in make-files that are
not part of the build system itself must be avoided. Instead, REP_DIR,
REP_INC_DIR, and $(call select_from_repositories, ...) should be used.
