arm64: dts: qcom: sm8550: Correct the min/max voltages for vreg_l6n_3p3

Voltage regulator 'vreg_l6n_3p3' max-microvolt prop is currently
configured at 3304000uV in different sm8550 board files. However this
is not a valid voltage value for 'pmic5_pldo502ln' type voltage
regulators.

Check below the max value(3200mV) in the regulator summary for min/max
used as 2800mV/3304mV in DT:-

logs:

[    0.294781] vreg_l6n_3p3: Setting 2800000-3304000uV

regulator summary:

---------------------------------------------------------------------
..
vreg_l6n_3p3   0    0    0     normal   2800mV   0mA  2800mV  3200mV
..

Correct the min/max value to 3200000uV, as that is the closest valid
value to 3.3V and Hardware team has also confirmed that its good to
support the consumers(camera sensors) of this regulator.
