Fix flashing with `MOST_RECENT_PORT=1` by detecting the board when
either in RIOT mode or in bootloader mode (which matches different
USB vendor and model strings).
Support for programming with the nrf52-u2f bootloader was dropped
apparently, but the documentation still recommends that over the
Arduino Bootloader. This brings doc and code in sync.
- add support for multiple timers
- add support for selecting clock source in the board's `periph_conf.h`
- add support for the prescaler
- implement `periph_timer_query_freqs`
- add a second timer to all MSP430 boards
- the first timer is fast ticking, high-power
- the second is slow ticking, low-power
When using `make flash` or `make term` with `MOST_RECENT_PORT=1`, RIOT
should now only consider plausible TTYs and select the most recently
connected one. The filter is a bit broad, though, and will match
any board with a CH430 UART2USB bridge. But depending on the boards
attached, it might be good enough to reliably tell it apart from
other boards.

When using `make flash` or `make term` with `MOST_RECENT_PORT=1`, RIOT
should now select relatively robustly the most recently connected
ESP32 Ethernet Kit / ESP32 Wrover Kit board, even with other TTYs
present. This is because the FTDI Dual RS232-HS with two USB2UART
bridges in the chip would be an expensive overkill for most boards,
unless one is using the FTDI chip to big-bang JTAG as well - as done
on the Ethernet Kit and Wrover Kit boards.
The board have one user button and a user led but are not enabled.
This add necessary support to use the button and the led. It include
the configs to use with SAUL and button interrupt.

- nRF51: Use `uart_conf_t` for consistency with nRF52
- nRF52832: Use UARTE (UART with EasyDMA) over UART (without DMA), as
done for all other nRF52 family members
- use `UARTE_PRESENT` to detect whether an UARTE can be used, rather
than family names
