[PATCH 1/1] spi: intel: Remove DANGEROUS tag from pci driver

[Mauro Lima]

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.
