regulator: max77802: Add input supply properties to DT binding doc

The max77802 regulator driver defines the supply name for each regulator
so these can be described in DT but is not mentioned in the binding doc.

regulators is still a node, so you should have 2 sections.

Hello Rob,

Thanks for your feedback.

You are right, I included both because I saw other DT bindings doing
this but agree the correct approach is to have two separate sections.

Mark already applied this patch though so I can't send a v2 but I'll
post an incremental patch on top of his topic/max77802 branch:

https://git.kernel.org/cgit/linux/kernel/git/broonie/regulator.git/log/?h=topic/max77802

Best regards,
