reset: npcm: fix iprst2 and iprst4 setting 

In NPCM8XX USB reset sequence, iprst2 register was set with iprst4 value
and iprst4 register wasn´t set.

This fix sets the correct IP reset values in iprst2 and iprst4 registers
in NPCM8XX USB reset sequence.

Fixes: fc5d2a2f4a ("reset: npcm: Add NPCM8XX support")
