ulp: fix calculation or ulp_run argument

Browse source 
The argument to ulp_run should be expressed in 32-bit words. Both the
address of ulp_entry and RTC_SLOW_MEM already are uint32_t*, so their
difference is the difference in addresses divided by sizeof(uint32_t).
Therefore the extra division by sizeof(uint32_t) is not needed.
