Subject: [PATCH v3 2/3] ARM: dts: imx6ull: add operating points

i.MX6ULL has different operating ranges than i.MX6UL so add the
operating points for the i.MX6ULL. A 25mV offset is added to the minimum
allowed values like for the i.MX6UL.

Signed-off-by: Sébastien Szymanski <sebastien.szymanski@...adeus.com>

Changes for v3:
 - none

Changes for v2:
 - Fix soc-operating-points voltage for 792MHz and 900MHz
