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 add support for the LED driver functionality of the
HT16K33.

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.

This adds interrupt support to the SAM0 GPIO driver. This is heavily
inspired by @nzmichaelh work in #5715. The primary difference
from that implementation is that here the External Interrupt
Controller (EIC) is separated out into an interrupt controller driver
that is less tightly coupled to the GPIO API. Instead it implements
more of a conversion from the EIC's own odd multiplexing to a more
traditional port and pin mask IRQ-like callback. Unfortunately,
through the EIC on the SAMD2x are relatively well behaved
in terms of pin to EIC line mappings, other chips that share the
peripheral interface are not. So the EIC driver implements a
per-line lookup to the pin and port pair using definitions extracted
from the ASF headers.
The EIC driver still makes some assumptions about how it will be used:
mostly it assumes exactly one callback per port. This should be fine
as the only intended user is the GPIO driver itself.
This has been tested with some simple programs and with
tests/drivers/gpio/gpio_basic_api on a SAMD21 breakout and an
adafruit_trinket_m0 board.

The PR removes the exclusive limit on enabling both UART_ASYNC_API
and UART_INTERRUPT_DRIVEN so that both options can be enabled
together for same uart driver.
Also, the interrupt handler will be used for both cases. So, enable
definition of interrupt handler for both.
However, nRF UART driver still wants to enable only one of them.
So, a new config is added to disable the code for UART_ASYNC_API
when the option UART_INTERRUPT_DRIVEN is enabled.

This adds support for the async API for SAM0 SERCOM SPI using
DMA to drive the device. This implementation does the reload
for both transmit and receive in the receive DMA handler.
Doing this simplifies the implementation but means that the
transmit drains completely, resulting in the SPI clock pausing
between buffers while both are reloaded in the receive handler.
Tested with tests/drivers/spi/spi_loopback and several simple
programs monitored with a logic analyzer.

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.
