drivers/periph/timer: Use uint32_t for frequency
...
For all currently supported platforms `unsigned long` is 32 bit in width. But
better use `uint32_t` to be safe.

cpu/fe310: RTC: use rtc_mktime()
...
Use RTC helper functions instead of libc functions.
This gives us y2038 safety by the extended epoch and saves
a good chunk of memory:
picolibc mktime():
text data bss dec hex filename

fe310: Use read-modify-store instruction on GPIO
...
The rv32imac supports the A (atomic) extensions containing
read-modify-store operations. This commit modifies the GPIO code to use
these for all bitwise operations. The atomic operations are emitted with
relaxed ordering as they do not require multiprocessor synchronization.
This decreases the duration of the gpio operations from 59 ns to 50 ns
per call. depending a bit on the type of operation.
