Stephen Boyd 4785cff7cb arm64: dts: sdm845: Add iommus property to qup 
The SMMU that sits in front of the QUP needs to be programmed properly
so that the i2c geni driver can allocate DMA descriptors. Failure to do
this leads to faults when using devices such as an i2c touchscreen where
the transaction is larger than 32 bytes and we use a DMA buffer.

arm-smmu 15000000.iommu: Unexpected global fault, this could be serious
arm-smmu 15000000.iommu:         GFSR 0x00000002, GFSYNR0 0x00000002, GFSYNR1 0x000006c0, GFSYNR2 0x00000000

Add the right SID and mask so this works.

* The hardware design intends this port to be hooked up in peripheral
* mode, so we'll hardcode it here. Some details:
* - SDM845 expects only a single Type C connector so it has only one
* native Type C port but cheza has two Type C connectors.
* - The only source of DP is the single native Type C port.
* - On cheza we want to be able to hook DP up to _either_ of the
* two Type C connectors and want to be able to achieve 4 lanes of DP.
* - When you configure a Type C port for 4 lanes of DP you lose USB3.
* - In order to make everything work, the native Type C port is always
* configured as 4-lanes DP so it's always available.
* - The extra USB3 port on SDM845 goes to a USB 3 hub which is then
* sent to the two Type C connectors.
* - The extra USB2 lines from the native Type C port are always
* setup as "peripheral" so that we can mux them over to one connector
* or the other if someone needs the connector configured as a gadget
* (but they only get USB2 speeds).
*
* All the hardware muxes would allow us to hook things up in different
* ways to some potential benefit for static configurations (you could
* achieve extra USB2 bandwidth by using two different ports for the
* two connectors or possibly even get USB3 peripheral mode), but in
* each case you end up forcing to disconnect/reconnect an in-use
* USB session in some cases depending on what you hotplug into the
* other connector. Thus hardcoding this as peripheral makes sense.
