HID: i2c-hid: Allow ACPI systems to specify "post-power-on-delay-ms"

Browse Source 
The property "post-power-on-delay-ms" allows a platform to specify
the delay needed after power-on, but only via device trees currently.
Use device_property_* instead of of_* reads to allow ACPI systems to
also provide the same information. This is useful for Wacom hardware
on ACPI systems.
