nvmem: qfprom: Increase fuse blow timeout to prevent write fail
sc7180 blow fuses got slightly chances to hit qfprom_reg_write timeout. Current timeout is simply too low. Since blowing fuses is a very rare operation, so the risk associated with overestimating this number is low. Increase fuse blow timeout from 1ms to 10ms.
