[PATCH v2 2/2] ARM: dts: am335x-bonegreen-eco: Enable 1GHz OPP by increasing vdd_mpu voltage

["Kory Maincent (TI.com)" <kory.maincent@bootlin.com>]

The vdd_mpu regulator maximum voltage was previously limited to 1.2985V,
which prevented the CPU from reaching the 1GHz operating point. This
limitation was put in place because voltage changes were not working
correctly, causing the board to stall when attempting higher frequencies.

With the recent TPS65219 PMIC driver fixes that properly implement the
LOCK register handling, voltage transitions now work reliably. Increase
the maximum voltage to 1.3515V to allow the full 1GHz OPP to be used.
