Ravi Kumar Bokka 9ec4f4b0e9 drivers: nvmem: Fix voltage settings for QTI qfprom-efuse
QFPROM controller hardware requires 1.8V min for fuse blowing.
So, this change sets the voltage to 1.8V, required to blow the fuse
for qfprom-efuse controller.

To disable fuse blowing, we set the voltage to 0V since this may
be a shared rail and may be able to run at a lower rate when we're
not blowing fuses.
