* Sunvell R69: cpu voltage regulator (re-)added - dram clock reduced.
CPU regulator (re-)added to u-boot and kernel dts - the box will not boot without it.
Dram clock reduced in defconfig to increase stability.

In current kernels (both next and dev) this patch breaks cpufreq and all that depends on it (no dvfs means board overheating). Removing it makes cpufreq and dvfs work again.
I've tested my OPi3 for best voltage numbers (for resolving stability problem after first patch), using StabilityTester and increasing slowly mV by 10 after every crash. Finaly, this values gives no error by running StabilityTester 100 times.
new values are based on stabilityTester results
when using 930mV for 1.6GHz and 980mV for 1.8GHz, xhpl failed randomly.
So 930/980mV are the critical operation voltage.Then increase 10mV and
run 100 times test, result shows that xhpl (not always) failed 1~2 times.
It seems +10mV is still not enough to ensure dc-dc output voltage always
above operation voltage, that means the design of dc-dc converter is not
good enough that results in large ripple.
The testing script is "github.com/mzhboy/StabilityTester"
The following configuration have been tested.
1.08-1.32-1.48-1.64-1.8 GHz
900-910-920-930-990 *ok, 930 failed 2/100
900-900-910-940-990 *ok, 990 failed 1/100
890-900-910-940-990 *ok, 990 failed 1/100
880-880-910-940-1000 *ok, 940 failed 2/100
880-880-910-950-1000 *ok, 1000 failed 1/100
880-880-910-950-1010 *ok
use more powerfull 'cpuburn-a53' to do pressure test.
power meter shows that 'cpuburn-a53' consumes much more power than
'stress -c 4' in the same condition. 930mV is not enough when running
'cpuburn-a53' meanwhile 950mV is the minimum voltage.
When running 'cpuburn-a53' at 1.8G, h6 consumes lots of power and generate
such amount of heat that an active cooling is necessary otherwise h6
gets overheat and system crashes. Even with active cooling and heatsink
is in low temperature the junction temperature is still quit high that
it reaches about 88~90 ℃ . Maybe the high thermal resistance of plastic
package causes the problem.
* [sunxi-dev][h6]update orangepi lite2 dts file patch
* [sunxi-dev][h6]update patch for sun50i-h6.dtsi
* [sunxi-dev][h6] new operation voltage table of allwinner h6
The correct operation voltages are find out after many reboots and test (over 20+).
the original 1.16v@1.64/1.8GHz was too high since standard cell voltage
of 28nm@HPC is 0.9v, h6 got overheat very quickly over 110 Celsius and then system hangs,
a power-cycle off is needed to reset soc.
I use 'stress -c 4' to do pressure test, with a medium size passive heatsink on top of h6.
The pressure test proves that the soc has about 4 watt power consuming
that is much lesser than original 6~7.x watt when running at 1.8GHz(orangepi lite2 with
usb Ethernet rtl8153 and usb hub, wifi is connected but not used).
Soc runs much more stable and does not get overheat easily under heavy load
with new opp table.
