spi: intel: Remove DANGEROUS tag from pci driver
Modern CPUs exposes this controller as PCI device that only uses
hardware sequencing capabilities which is safer than software
sequencing.
Leave the platform driver as *DANGEROUS* and update help text since
most of these controllers are using software sequencing.
