soc: nordic: vpr: remove enabling MSTATUS.MIE in boot time

Browse source 
Interrupts should not be enabled this early in boot time.
Driver initializations expect IRQs not to arrive when
setting up HW.
Remove enabling `MSTATUS.MIE` in `__start`.
It will be enabled when main thread is switched to,
as threads by default start with enabled `MSTATUS.MIE`.
