We can utilize the devicetree macros to determine which instances to
enable. This will allow us to phase out the per instance Kconfig
symbols.

This reverts commit 90cc723e65.
Using `DMAC_CHCTRLA_TRIGACT_BLOCK` breaks SERCOM UART peripheral DMA
operations (DMA-based asynchronous UART transmit operation only sends
the first byte and does not proceed any further).
The `DMAC_CHCTRLA_TRIGACT_BURST` with `DMAC_CHCTRLA_BURSTLEN(0)` is a
special case utilising the "internal FIFO", according to the datasheet
(see DS60001507E; 22.6.2.8), and should always be specified for
peripheral data transfer operations.
Also it is worth noting that Atmel and other third-party drivers use
the aforementioned "internal FIFO" configuration for peripheral data
transfers as well.

The channel direction for a V1 DMA is not allowed to be memory to memory
and there is a check in place for this. However, the check is being
performed on the stream prior to actually configuring the stream. This
results in the check always failing regardless of the channel direction.
The check has been modified to be performed on the incoming
configuration.

Following other drivers, Kconfig based instances are now entirely
removed. In order to do this change, PWM nodes in board DT files have
been given a pwm{N} label so that both:
- DT API checks such as #if DT_HAS_NODE(DT_NODELABEL(pwmN)) can be
used (N being PWM instance number).
- DT references can be written as pwms = <&pwmN x y>; instead of
pwms = <&{/soc/timers@XXXXXXXX/pwm} x y>;
This approach is also used on the Linux Kernel.

The optimisation in `spi_sam0_fast_txrx()` is broken, loading
two bytes into the `DATA` register in rapid succession will lose
one byte.
This can be observed by running `tests/drivers/spi/spi_loopback`.
The test will get stuck in `spi_sam0_fast_txrx()` forever waiting
for the final byte.
Undo this small optimisation and only load the next byte into the
`DATA` register after the response has been received.
This fixes `tests/drivers/spi/spi_loopback`.

The PS/2 driver was enabled with a single mouse and kb brand.
However, when plugging other mice brands, the interaction between the

the PS/2 instance helped the internal FSM to start the TX process.

The RTC/Counter implementation doesn't fit for the upcoming LoRaWAN
as most of the Counter drivers in Zephyr works with 1s granularity
which is not enough for LoRaWAN stack. So, k_timer calls are used in
place of Counter's alarm and k_uptime_get() APIs are used in place of
Counter's time keeping.
While at it, lets also fixup the broken alarm implementation.

Replace having dts_fixup.h files define DT_ADC_{0..2}_NAME with using
the new devicetree.h macros. We test to see what driver compat is
enabled via DT_HAS_COMPAT and set DT_DRV_COMPAT to that compat. Than we
can utilize the DT_INST_LABEL() macro to extract the name of the device.
We also replace the Kconfig ADC_{0..2} symbols with DT_HAS_DRV_INST.
This will allow us to remove those Kconfig symbols as this was the only
usage.
