mb/intel/ptlrvp: Add power meter acpi changes

Browse source 
This commit introduces changes to the ACPI implementation for the
PTLRVP mainboard by adding power meter support. It defines how the
PAC194x series devices are connected to the I2C controller and details
their configuration. Each device under scope \_SB.PCI0.I2C3 is given
specific methods to indicate its status, resource settings, and device
specific configurations via _DSM. This includes functionality to return
monitored power rail names, resistor values, EMI configurations, sample
frequencies, and Vbus multiplication factors. These changes enhance
the power management capabilities of the mainboard, allowing precise
monitoring and control over various power rails.

BUG=none
TEST=Verify power meter ACPI changes in DSDT.
