Various places in the code set "boardname" env property. It was used
for booting from ITB images and choosing proper DTB file name. Instead
of duplicating it, use existing U-Boot wide - "board_name".

Printing the "Type" of board requires proper detection of revision which
can happen only late because regulators are needed.

Changing voltage and enabling regulator might require delays so the
regulator stabilizes at expected level.
Add support for "regulator-ramp-delay" binding which can introduce
required time to both enabling the regulator and to changing the
voltage.

According to datasheet, the output on LDO regulators will start
appearing after 10-15 us.

LDOs is unknown, it seems safer to use at least some value from
reference kernel than to leave it unset.

2. Turning VDD_ADC should wait with ramp delay,
3. Reading the value from ADC should wait for it to stabilize.
Tested on Odroid XU3-Lite and Odroid HC1.
