A lot of drivers were getting platform and of headers
indirectly via headers like asm/pci.h or asm/prom.h
Most of them were fixed during 5.19 cycle but a newissue was
introduced by commit 52b1b46c39ae ("of: Create platform devices
for OF framebuffers")
Include missing platform_device.h to allow cleaning asm/pci.h

powerpc's asm/prom.h brings some headers that it doesn't need itself.
Once those headers are removed from asm/prom.h, the following
errors occur:
CC [M] drivers/scsi/cxlflash/ocxl_hw.o

cc1: some warnings being treated as errors
Fix it by including linux/irqdomain.h

I assume you take this through the linuxppc git tree?
