[PATCH v2 0/6] Convert MIPS Malta boards to PCI DM

[Daniel Schwierzeck]

This series converts the PCI host controller drivers used by MIPS
Malta and the board-specific PCI setup code to PCI driver model.
Because the AMD PCNET driver is already converted to ETH driver
model, simply enable CONFIG_DM_ETH as well.

A patch in PCI uclass core is currently required for MIPS wanting
to use PCI DM (except Octeon MIPS64) due to CONFIG_SYS_SDRAM_BASE
being used as a virtual address on all MIPS boards.

The series for now is only tested with Qemu and the GT64120 PCI
controller. The Malta Qemu tests are already covered by U-Boot CI
Support for the MSC01 controller is prepared. The used PCI controller
depends on the plugged core card (Qemu emulates the CoreLV card with
GT64120).

Dynamic selection of the according PCI DT nodes via CONFIG_OF_BOARD_FIXUP
is prepared but not yet enabled. This requires fixing of the call order of
fix_fdt() in board_init_f, otherwise the passed-in rw_fdt_blob pointer
will point to a read-only NOR flash address. I'll send a separate
RFC patch for this.

I'll send a cleanup series for removing non-DM code after the merge
windows has closed and the PCI DM conversion deadline has been
enforced.

Changes in v2:
- add empty line before return statements
- add empty line before return statements
- use dm_pci_clrset_config32() where possible
