[PATCH 0/8] Make several Kconfig options depend on HAS_IOMEM

[Baoquan He]

In thread of one patch posting, LKP test robot reported some compiling
errors, paste the LKP report link here: 

https://lore.kernel.org/all/202306211329.ticOJCSv-lkp@xxxxxxxxx/T/#u

In the config file, several Kconfig options are like below:
------
'# CONFIG_PCI is not set'
CONFIG_OF_EARLY_FLATTREE=y
CONFIG_DMA_DECLARE_COHERENT=y
------

The reason is (words arranged from Niklas):
===
On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common
than PCI devices. Hence it could have a fully functional s390 kernel
with CONFIG_PCI=n, then the relevant iomem mapping functions
[including ioremap(), devm_ioremap(), etc.] are not available.

So make several Kconfig options depend on HAS_IOMEM so that it won't
build in those driver code if PCI is unset.
