According to the board porting guidelines, boards should "leave
peripherals and their drivers disabled by default". In Zephyr we
tipically enable GPIO and SERIAL, as they are virtually required by all
samples/tests in tree. However, for the rest of peripherals it is up to
the application/test to enable the necessary driver classes. It is also
useful that board's Kconfig.defconfig enables certain driver peripherals
based on a condition, e.g. enable I2C if SENSOR=y.
Ref. https://docs.zephyrproject.org/latest/hardware/porting/
board_porting.html#general-recommendations
This patch removes the following driver classes from defconfig files:
- CONFIG_ADC
- CONFIG_COUNTER
- CONFIG_EEPROM
- CONFIG_ENTROPY
- CONFIG_ESPI
- CONFIG_HWINFO
- CONFIG_I2C
- CONFIG_LED
- CONFIG_NETWORKING
- CONFIG_PS2
- CONFIG_PWM
- CONFIG_SENSOR
- CONFIG_SPI
- CONFIG_SPI_SLAVE
- CONFIG_WATCHDOG
Note that a previous attempt was done in #38510.

Updated all PWM specs to include the period cell. Because all specs
refer to PWM driven LEDs, a period of 20 msec has been chosen, as most
other platforms do.

After pinmux being converted to build a separate static library
console not show anymore and there is a hard fault. The hard
fault happen because pinmux drivers are not ready yet and board
emits an assert. This change board pinmux initialization to
PRE_KERNEL_2 and let system take care error handling.

USB devicetree nodes in Zephyr have different names,
mostly derived from the designations in data sheets.
Add zephyr_udc0 (USB device controller) nodelabel to
specific USB node to allow generic USB sample to be build.

Some boards, e.g. atsamd20_xpro, enable non-minimal peripherals by
default like SPI. This goes against board porting guidelines, as it
enables a peripheral that is not necessarily used by all samples,
as discussed at #30694. This removes SPI as a default peripheral
for all sam/sam0 boards.

The USB option alone only caused the driver to be built
and actually has no benefit. Remove it from *_defconfig files.

Add Atmel sam0 sercom[uart] pinctrl bindings and implements pinctrl at
driver level. It changes all sam0 boards to use new feature and remove
pinmux driver dependency for sercom[uart]. The samples that require a
binding were update to keep consistency and avoid errors.

Switch to use DEVICE_DT_GET instead of device_get_binding for pinmux
device. As part of this change drop the "label" property from
the pinmux devicetree node and update the binding and dts files to
reflect that.

Surpress the warning for those cases:
