Rename sn65dsi83 to sn65dsi84 as that is the exact chip used on the
Verdin DSI to LVDS Adapter.

From: Philippe Schenker <philippe.schenker@toradex.com>
Currently, we limited the voltages from the PMIC very strictly. This
causes an issue with one Toradex SKU that uses a consumer-grade chip
that is capable of going up to 1.8GHz at 1.00V.
Extend the ranges to min/max values of the SoC operating ranges (table
10) in the datasheet. Detailed explanation as follows:
BUCK2:
- As already described above, the SKU with the consumer-grade chip
needs a voltage of at least 1.00V. 1.05V is chosen now as this is
listed as the maximum. Both industrial and consumer-grade chips have
an absolute maximum rating of 1.15V which makes it still safe to put
1.05V
- Lower the regulator-min value to the smallest value allowed from the
Quad-A53, 1.2GHz version of the SoC
BUCK3:
- This regulator is used for SoC input voltages VDD_GPU, VDD_VPU and
VDD_DRAM.
- Use the smallest value of these three inputs as the regulator-min
- Use the largest value of these three inputs as the regulator-max
LDO2:
- This LDO is used for VDD_SNVS_0P8 SoC input voltage. As this has a
single nominal input voltage just put this in the middle of 0.8V.
