Subrata Banik 57cd50cd6a ichspi: Add support for Panther Lake 
This patch adds Panther Lake support into flashrom as per Intel
Panther Lake SPI programming doc, number: 815466.

BUG=b:347669091
TEST=Flashrom is able to detect PTL SPI DID and show chipset name as
below:

> flashrom --flash-name
....
Found chipset "Intel Panther Lake-U/H 12Xe".
....
> flashrom -p internal --ifd -i fd -i bios -r /tmp/bios.rom
....
Reading ich_descriptor... done.
Assuming chipset 'Panther Lake'.
Using regions: "bios", "fd".
Reading flash... done.
SUCCESS

flashrom README
===============

flashrom is a utility for detecting, reading, writing, verifying and erasing
flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images
in-system using a supported mainboard, but it also supports flashing of network
cards (NICs), SATA controller cards, and other external devices which can
program flash chips.

It supports a wide range of flash chips (most commonly found in SOIC8, DIP8,
SOIC16, WSON8, PLCC32, DIP32, TSOP32, and TSOP40 packages), which use various
protocols such as LPC, FWH, parallel flash, or SPI.

Do not use flashrom on laptops (yet)! The embedded controller (EC) present in
many laptops might interact badly with any attempts to communicate with the
flash chip and may brick your laptop.

Please make a backup of your flash chip before writing to it.

Please see the flashrom(8) manpage :doc:`classic_cli_manpage`.
