MLK-14510: ARM: dts: imx6ull-14x14-ddr3-arm2: fix pfuze200 probe error

SW3B fused to high voltage 0.8v~3.3v and the low voltage setting in
dts cause pfuze200 driver probe failed as below even if the pfuze
driver have already updated the voltage to the right 0.8v~3.3v.But the
issue not caught on v4.1 since it's common regualtor framework behavior.
Correct the SW3B into the right voltage in v4.9

fuze100-regulator 0-0008: pfuze200 found.
SW3B: Bringing 3300000uV into 1975000-1975000uV
SW3B: failed to apply 1975000-1975000uV constraint(-22)
pfuze100-regulator 0-0008: register regulatorSW3B failed
pfuze100-regulator: probe of 0-0008 failed with error -22
