spi: intel-pci: Meteor Lake fix and Arrow Lake PCI ID

Hi,

The Meteor Lake-S SPI-NOR PCI ID is for a controller that does not support all the necessary operations so the first patch removes that from the driver. Second one adds the correct one (the same is used in Arrow Lake).

Turns out this "SoC" side controller does not support certain commands, such as reading chip JEDEC ID, so the controller is pretty much unusable in Linux. We should be using the "PCH" side controller instead. For this reason remove this PCI ID from the list.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks,
Mark

This adds the PCI ID of the Arrow Lake and Meteor Lake-S PCH SPI serial flash controller. This one supports all the necessary commands Linux SPI-NOR stack requires.
