regulator: pfuze100: update voltage setting for pfuze3000 sw1a
pfuze3000 datasheet(Rev.9.0) from:
https://www.nxp.com/docs/en/data-sheet/PF3000.pdf
updates sw1a's voltage range, the settings for 1.450V and 1.475V
are replaced with 1.8V and 3.3V:
5b'11110 1.450 (SW1B), 1.8 (SW1A/SW1AB)
5b'11111 1.475 (SW1B), 3.3 (SW1A/SW1AB)
the voltage calculation using steps is NOT available for sw1a now,
use voltage table instead.
