[U-Boot] [PATCH v3 0/8] dm: pci: tegra: Convert Tegra PCI to driver model

This series converts all Tegra boards to use driver model for PCI. The net
effect should be no change in functionality.

A few additional features are added to make this possible:
- Helper functions to support accessing 8- and 16-bit values within a 32-bit
  word
- Fixing a build error for CONFIG_CMD_PCI_ENUM
- Decoding the PCI ranges property such that configuration ranges are
  ignored
- Supporting bus-master devices on boards where RAM does not start at 0

This series is tested on beaver. It is available at u-boot-dm/tegra-working.

Changes in v3:
- Rebase onto tegra/master

Changes in v2:
- Update commit message to explain that the feature is not important
- Drop the feature from tegra boards
- Rename 'addr' to 'size'
- Correct logic for use of gd->pci_ram_top
- Update commit message to mention future work
- Use the device_is_on_pci_bus() API
- Leave pci_skip_dev() at the bottom of the file to reduce the diff size
