boards: remove non-minimal peripherals from defconfig

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.

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.

Fixes #30694
