mx53loco: Add support for 1GHz operation for DA9053-based boards
There are two types of mx53loco boards: initial boards were built with a Dialog
DA9053 PMIC and more recent version is based on a Freescale MC34708 PMIC.
Add DA9053 PMIC support and adjust the required voltages and clocks for running
the CPU at 1GHz.
Tested on both versions of mx53loco boards.
In the case of a MC34708-based board the CPU operating voltage remains at 800MHz.
