drivers/periph_gpio: let gpio_read() return bool 
Since https://github.com/RIOT-OS/RIOT/pull/20935 gpio_write()
uses a `bool` instead of an `int`. This does the same treatment for
`gpio_read()`.

This does indeed add an instruction to `gpio_read()` implementations.
However, users caring about an instruction more are better served with
`gpio_ll_read()` anyway. And `gpio_read() == 1` is often seen in
newcomer's code, which would now work as expected.

drivers/periph/gpio_ll: pass gpio_conf_t by value 
Now that `gpio_conf_t` is on all implemented platforms no larger than
a register, we can more efficiently pass it by value rather than via
pointer.

drivers/periph/gpio_ll: shrink gpio_conf_t 
This commit optimizes the `gpio_conf_t` type in the following
regards:

- The "base" `gpio_conf_t` is stripped from members that only some
  platforms support, e.g. drive strength, slew rate, and disabling of
  the Schmitt Trigger are no longer universally available but
  platform-specific extensions
- The `gpio_conf_t` is now crammed into a bit-field that is 8 bit or
  16 bit wide. This allows for storing lots of them e.g. in
  `driver_foo_params_t` or `uart_conf_t` etc.
- A `union` of the `struct` with bit-field members and a `bits` is used
  to allow accessing all bits in a simple C statement and to ensure
  alignment for efficient handling of the type

54e915e40d cpu/efm32/timer_series2: sync STATUS register 
Make sure the STATUS register has been synced between the different clock domains.

Especially the LETIMER needs some time to update the STATUS register after it has been enabled. If the LETIMER is started and stopped with just a short delay, pm_layered gets confused because the timer seems to be inactive ...

bad385ab7c cpu/efm32: RTC Series 0: use RTC helper functions 
By using the RTC helper functions instead of POSIX mktime()/gmtime()
we can not only extend the RTC range beyond Y2038.

For tests/periph_rtc:

before:

   text	   data	    bss	    dec	    hex	filename
  28028	    248	   2472	  30748	   781c stk3700/tests_periph_rtc.elf

after:

   text	   data	    bss	    dec	    hex	filename
  19400	    144	   2424	  21968	   55d0 stk3700/tests_periph_rtc.elf
