Subject: [PATCH v6 0/6] staging: vc04_services: vchiq: Register devices with a custom bus_type

This series just introduces five extra patches for dropping include
directives from Makefiles (suggested by Greg KH) and rebased.

The main patch (6/6) removes platform device/driver abuse and moves
things to standard device/driver model using a custom_bus. Specific
details are elaborated in the commit message.

The patch series is based on top of d514392f17fd (tag: next-20230120)
of linux-next.

Changes in v6:
- Split struct device and struct driver wrappers in vchiq_device.[ch]
- Move vchiq_bus_type definition to vchiq_device.[ch] as well
- return error on bus_register() failure
- drop dma_set_mask_and_coherent
- trivial variable name change

Changes in v5:
- Fixup missing "staging: " in commits' subject line
- No code changes from v4

Changes in v4: 
- Introduce patches to drop include directives from Makefile

Changes in v3:
- Rework entirely to replace platform devices/driver model
