[U-Boot] [PATCH v2 0/17] dm: x86: Convert x86 to use driver model more fully

[Simon Glass]

At present x86 does not use driver model for SPI or LPC (low-pin-count, a
bus used to talk to the EC on Chromebooks).

This series:
- moves the ICH SPI driver over to driver model
- moves the cros_ec LPC driver to driver model
- removes non-driver-model cros_ec code (since now I2C, SPI and LPC are
    converted over)
- makes some use of the PCI uclass for x86 init, by no means complete
- fixes up the keyboard to work on chromebook_link (previously it would only
    work when started from coreboot)

Changes in v2:
- Support pre-driver-model too so we can rebase on dm/next
- Adjust snow to move cros_ec from SPI to I2C
- Add new patch to move CONFIG_CROS_EC_SANDBOX to Kconfig
- Rebase to dm/next
