ipq806x: fix min<>target opp-microvolt DTS mixup

Browse Source 
Rearrange all voltage triplets for "opp_table0" to match the
specifications.  "opp-microvolt" and "opp-microvolt-<name>" triplets
are in order of <target min max>, and NOT <min target max>.

Previously, the CPU would *always* spend its time at the "minimum"
voltage, ignoring the actual intended target.  This is a regression
from previous behavior.

On an NBG6817 with a Qualcomm CPU of PVS bin #2...
(see &opp_table0 -> opp-1725000000 -> opp-microvolt-speed0-pvs2-v0)

* Before:
/usr/bin/tail -n +1 /sys/kernel/debug/opp/cpu0/opp\:1725000000/supply-0/u_volt_*
==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_max <==
1260000

==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_min <==
1200000

==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_target <==
1140000

* After:
/usr/bin/tail -n +1 /sys/kernel/debug/opp/cpu0/opp\:1725000000/supply-0/u_volt_*
==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_max <==
1260000

==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_min <==
1140000

==> /sys/kernel/debug/opp/cpu0/opp:1725000000/supply-0/u_volt_target <==
1200000

To check voltages and frequencies at run time, use...
/bin/cat /sys/kernel/debug/regulator/regulator_summary &&
  /bin/cat /sys/kernel/debug/clk/clk_summary | grep "hfpll"
