staging: pi433: use div_u64 for 64-bit division
I ran into this link error on an ARM OABI build:
drivers/staging/pi433/rf69.o: In function `rf69_set_frequency':
rf69.c:(.text+0xc9c): undefined reference to `__udivdi3'
No idea why I didn't see it with the default EABI configurations,
but the right solution here seems to be to use div_u64()
to get the external division implementation.
Fixes: 874bcba65f9a ("staging: pi433: New driver")
