Move tempmon, ldb and pmu nodes from soc node to root node.

The nodes that have been moved do not have any register properties and thus
shouldn't be placed on the bus.

The timer fixed interval period pulse generator register
is used to generate periodic pulses. The down count
register loads the value programmed in the fixed period
interval (FIPER). At every tick of the timer accumulator
overflow, the counter decrements by the value of
TMR_CTRL[TCLK_PERIOD]. It generates a pulse when the down
counter value reaches zero. It reloads the down counter
in the cycle following a pulse. To use the TMR_FIPER1
register to generate a 1 PPS event, the value
(10^9 nanoseconds) - TCLK_PERIOD should be programmed.
It should be 999999995 not 999999990 since TCLK_PERIOD
is 5.

UDOO board has a possibility to disable most of imx6 SoC power supplies via
"EN_5V" signal, which is connected to "NANDF_D4" pad.

This reduces current consumption after shutdown from ~350 mA to ~40 mA and
prevents a SoC watchdog from starting it again on its own after the
watchdog timeout expires (previously it was not possible to shut down the
SoC permanently if its watchdog was ever enabled since it was still ticking
after the shutdown).

Unfortunately, this does not extinguish the "Power" LED (as it is powered
from an always-on voltage regulator).

To power the SoC up again press the power button (SW2, the one with a long
shaft).
