As per the schematic Monolithic Power Systems MP2161GJ-C499
supply a fixed output voltage of 5.0V. This supplies linked
to VDD_EE, HDMI_P5V0, USB_POWER, VCCK, VDDIO_AO1V8, DDR_VDDC
according to the schematics.

Changes from my previous attempt below
[1] https://lore.kernel.org/patchwork/patch/1031243/

New patch and fix the commit message.
Added regulator-always-on since this is core input regulator.
Split the linking on regulator and usb node in separate patch.

Later more patchs will follow linking more core regulator as per
shematics.
