The HT16K33 is a memory mapping, multifunction LED controller
driver. The controller supports up to 128 LEDs (up to 16 rows and 8
commons) and matrix key scan circuit of up to 13x3 keys.
This commit adds support for the keyscan functionality of the HT16K33.

Unfortunately, Zephyr SDK 0.10.0 ships with outdate Newlib 2.0.0
(from 2015 or earlier) which lacks sys/_timeval.h header, requiring
ugly workaround of defining struct timeval inline (the whole idea
was to standardize on sys/_timeval.h header for different libc's).
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
According to POSIX, that's the header which defines this function.
Similarly, nothing in POSIX indicates that <time.h> should have
access to struct timeval, so it's removed (it's made accessible
to <sys/time.h> via <sys/_timeval.h> introduced earlier).

Some applications using DMA, such as UART RX, could
need to complete the current DMA transaction earlier than
predefined, based on other termination conditions,
like UART's IDLE interrupts.
In that case, the client needs to know how many data are
still left in DMA transfer buffer so that it can figure
out how many data has been transfered. However, the current
DMA API doesn't provide any information for the client
to learn the transfer buffer information.
And some other information, like whether DMA transfer is busy
or not, transfer direction, etc, could interest a client.
So, added a dma API function to retrieve the current DMA
runtime status.
And implemented the API for STM32F4's DMA while keeping
others unimplemented.

The ARM Cortex-M Exception Stack Frame (ESF) may consist of

It will help to use IS_ENABLED in place of #ifdef in relevant place.
Only struct net_if uses this structure.
In case only IPv4 is used, it will bloat up this struct by 12 bytes.
There are few reasons why this is "ok" in this case:
- On limited rom/ram system it will be unlikely to find a lot of
network interfaces so it should not harm much to raise the size of
struct net_addr.
- If IPv4 is the only enabled IP version, it gains a good amount of
rom/ram to discard IPv6 support so it is fine to steal a bit of this
gain to bloat up a bit struct net_addr.

However, nRF UART driver still wants to enable only one of them.

A new function pcie_irq_enable() is added to be used in lieu of
irq_enable() when the target device is PCI(e)-attached. The function
attempts to use MSI, when configured in the kernel and supported by
the endpoint; failing that, it will verify that IRQ requested is in
fact routed to the device by the boot firmware before enabling it.
The NS16550 UART driver is updated to use pcie_irq_enable().
The PCI(e) shell is extended to dump information about wired IRQs.
The up_squared devicetree is fixed (reverted?) to IRQ5 for UART1.
The galileo enables MSI by default.

to immediately follow the net_buf_simple struct.

A parallel PCI implementation ("pcie") is added with features for PCIe.
In particular, message-signaled interrupts (MSI) are supported, which
are essential to the use of any non-trivial PCIe device.
The NS16550 UART driver is modified to use pcie.
pcie is a complete replacement for the old PCI support ("pci"). It is
smaller, by an order of magnitude, and cleaner. Both pci and pcie can
(and do) coexist in the same builds, but the intent is to rework any
existing drivers that depend on pci and ultimately remove pci entirely.
This patch is large, but things in mirror are smaller than they appear.
Most of the modified files are configuration-related, and are changed
only slightly to accommodate the modified UART driver.
Deficiencies:
64-bit support is minimal. The code works fine with 64-bit capable
devices, but will not cooperate with MMIO regions (or MSI targets) that
have high bits set. This is not needed on any current boards, and is
unlikely to be needed in the future. Only superficial changes would
be required if we change our minds.
The method specifying PCI endpoints in devicetree is somewhat kludgey.
The "right" way would be to hang PCI devices off a topological tree;
while this would be more aesthetically pleasing, I don't think it's
worth the effort, given our non-standard use of devicetree.
