soc/intel/ptl: Add Wildcat Lake SKU power map

Browse source 
Add mapping of different SKUs based on CPU ID and TDP values.
Add PowerLimits (PL) values.
Add i_trip value for Fast Vmode.

Note: The i_trip value, the value at which the Voltage Regulator (VR)
or SoC will trigger a protective action such as throttling or
entering Fast Vmode is, due to not being documented, currently set at
70% of the maximum current the VR is designed to support for a rail.
The actual i_trip value to be updated once it is available.

Ref=858124 Power Delivery Guide Rev1p0
    830097 Powermap Rev1p1

BUG=b:433211504
TEST= Build Ocelot and verify it compiles without any error.
check CPU log for the following error

    [ERROR]  Could not find the SKU power map

With the current patch this error line is not seen in the CPU log
anymore.
