cfg80211: remove enum station_info_flags
This is really just duplicating the list of information that's
already available in the nl80211 attribute, so remove the list.
Two small changes are needed:
* remove STATION_INFO_ASSOC_REQ_IES complete, but the length
(assoc_req_ies_len) can be used instead
* add NL80211_STA_INFO_RX_DROP_MISC which exists internally
but not in nl80211 yet
This gets rid of the duplicate maintenance of the two lists.

ARM64: dts: define reserved mapping for bootloader's splash screen
Bootloader on TM2 board enables DECON and sets it to display splash
screen. To let Linux kernel to properly initialize IOMMU and devices
during probe time, additional identity mappings are needed. This patch
adds iommu-reserved-mapping property and sets up ideantity mapping for
the whole RAM available on the board.

iommu: implement common IOMMU ops for DMA mapping
Taking inspiration from the existing arch/arm code, break out some
generic functions to interface the DMA-API to the IOMMU-API. This will
do the bulk of the heavy lifting for IOMMU-backed dma-mapping.
Whilst this RFC series is aimed at enabling arm64, once any remaining
obvious issues in the common code are addressed we can complete the
refactoring by porting arch/arm over for a merge-worthy series.

ARM: dts: exynos: add iommu reserved regions for bootloader's splash screen
Some bootloaders enable FIMD module and configure it as a simple
framebuffer to display boot logo or splash screen before booting the
kernel. Such framebuffer stays enabled until proper kernel driver gets
probbed. Usually it is configured in such a way, that it performs DMA
from the buffer located in system memory. To avoid IOMMU access fault
during system boot, additional identity mapping between system memory
and IO virtual address space must be created when IOMMU driver gets
enabled.
