irqchip: remove MODULE_LICENSE in non-modules
Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as
modules.

iommu/dma: Move public interfaces to linux/iommu.h
The iommu-dma layer is now mostly encapsulated by iommu_dma_ops, with
only a couple more public interfaces left pertaining to MSI integration.
Since these depend on the main IOMMU API header anyway, move their
declarations there, taking the opportunity to update the half-baked
comments to proper kerneldoc along the way.

irqchip/ls-scfg-msi: Don't map the MSI page in ls_scfg_msi_compose_msg()
ls_scfg_msi_compose_msg() may be called from non-preemptible context.
However, on RT, iommu_dma_map_msi_msg() requires to be called from a
preemptible context.
A recent patch split iommu_dma_map_msi_msg() in two new functions:
one that should be called in preemptible context, the other does
not have any requirement.
The FreeScale SCFG MSI driver is reworked to avoid executing preemptible
code in non-preemptible context. This can be achieved by preparing the
MSI maping when allocating the MSI interrupt.

irqchip/ls-scfg-msi: Add MSI affinity support
For LS1046a and LS1043a v1.1, the MSI controller has 4 MSIRs and 4 GIC
SPI interrupts which can be associated with different Core.
So we can support affinity to improve the performance.
The MSI message data is a byte for Layerscape MSI.
7 6 5 4 3 2 1 0
| - | IBS | SRS |
SRS bit0-1 is to select a MSIR which is associated with a CPU.
IBS bit2-6 of ls1046, bit2-4 of ls1043a v1.1 is to select bit of the
MSIR. With affinity, only bits of MSIR0(srs=0 cpu0) are available.
All other bits of the MSIR1-3(cpu1-3) are reserved. The MSI hwirq
always equals bit index of the MSIR0. When changing affinity, MSI
message data will be appended corresponding SRS then MSI will be
moved to the corresponding core.
But in affinity mode, there is only 8 MSI interrupts for a controller
of LS1043a v1.1. It cannot meet the requirement of the some PCIe
devices such as 4 ports Ethernet card. In contrast, without affinity,
all MSIRs can be used for core 0, the MSI interrupts can up to 32.
So the parameter is added to control affinity mode.
"lsmsi=no-affinity" will disable affinity and increase MSI
interrupt number.

A MSI controller of LS1043a v1.0 only includes one MSIR and

LS1043a v1.1 MSI is assigned 4 MSIRs and 4 GIC interrupts.
But the MSIR has the different offset and only supports 8 MSIs.
The bits between variable bit_start and bit_end in structure
ls_scfg_msir are used to show 8 MSI interrupts. msir_irqs and
msir_base are added to describe the difference of MSI between
LS1043a v1.1 and other SoCs.

ls_scfg_msi_compose_msg() may be called from non-preemptible context.
However, on RT, iommu_dma_map_msi_msg() requires to be called from a
preemptible context.
A recent patch split iommu_dma_map_msi_msg() in two new functions:
one that should be called in preemptible context, the other does
not have any requirement.
The FreeScale SCFG MSI driver is reworked to avoid executing preemptible
code in non-preemptible context. This can be achieved by preparing the
MSI maping when allocating the MSI interrupt.

irqchip/ls-scfg-msi: Add MSI affinity support
For LS1046a and LS1043a v1.1, the MSI controller has 4 MSIRs and 4 GIC
SPI interrupts which can be associated with different Core.
So we can support affinity to improve the performance.
The MSI message data is a byte for Layerscape MSI.
7 6 5 4 3 2 1 0
| - | IBS | SRS |
SRS bit0-1 is to select a MSIR which is associated with a CPU.
IBS bit2-6 of ls1046, bit2-4 of ls1043a v1.1 is to select bit of the
MSIR. With affinity, only bits of MSIR0(srs=0 cpu0) are available.
All other bits of the MSIR1-3(cpu1-3) are reserved. The MSI hwirq
always equals bit index of the MSIR0. When changing affinity, MSI
message data will be appended corresponding SRS then MSI will be
moved to the corresponding core.
But in affinity mode, there is only 8 MSI interrupts for a controller
of LS1043a v1.1. It cannot meet the requirement of the some PCIe
devices such as 4 ports Ethernet card. In contrast, without affinity,
all MSIRs can be used for core 0, the MSI interrupts can up to 32.
So the parameter is added to control affinity mode.
"lsmsi=no-affinity" will disable affinity and increase MSI
interrupt number.
