c6646125f7 native/mtd: drop .write() 
The old .write() function is only used as a fall-back if .write_page()
is not implemented.
We can drop it.

cpu/stm32: fix periph_i2c for F1, F2, L1 and F4 families 
- boot the I2C after init in low power mode
    - otherwise I2C will consume more power until the first time it is
      used, which is surprising
- STM32 F1 only: reconfigure SCL and SDA as GPIOs while the I2C
  peripheral is powered down
    - When the I2C peripheral is not clocked, it drives SCL and SDA
      down. This will dissipate power across the pull up resistor.

cpu/msp430: improve periph_timer 
- 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

cpu/nrf5x_common: clean up UART implementation 
The functions `uart_poweron()`, `uart_poweroff()` and  `uart_mode()`
can share code between the UART (UART without EasyDMA) and UARTE
(UART with EasyDMA) implementations, so let's do that.

cpu/nrf5x: clean up periph_uart 
- 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

cpu/nrf51: fix periph_i2c driver 
The `i2c_read_bytes()` and `i2c_write_bytes()` function return the
number of bytes written / read, instead of `0` as the API contract
says. This fixes the issue.

cpu/stm32/periph_spi: improve prescaler calculation 
With only 8 possible prescalers, we can just loop over the values
and shift the clock. In addition to being much easier to read, using
shifts over divisions can be a lot faster on CPUs without hardware
division.

In addition an `assert()` is added that checks if the API contract
regarding the SPI frequency is honored. If the requested clock is too
low to be generated, we should rather have a blown assertion than
hard to trace communication errors.

Finally, the term prescaler is used instead of divider, as divider may
imply that the frequency is divided by the given value n, but
in fact is divided by 2^(n+1).

cpu/stm32/periph_spi: Fix /CS handling 
Previously, the /CS signal was performed by enabling / disabling the
SPI peripheral. This had the disadvantage that clock polarity settings
where not applied starting with `spi_acquire()`, as assumed by e.g.
the SPI SD card driver, but only just before transmitting data.

Now the SPI peripheral is enabled on `spi_acquire()` and only disabled
when calling `spi_release()`, and the `SPI_CR2_SSOE` bit in the `CR2`
register is used for hardware /CS handling (as supposed to).

cpu/stm32: Provide spi_mode_t 
This doesn't change the firmware, since for all STM32 MCUs with an
SPI driver the register setting in the mode did match the SPI mode
number by chance. But for some STM32 MCUs with no SPI driver yet
the register layout is indeed different. This will help to provide an
SPI driver for them as well.
