Sudeep Holla bf36619a54 firmware: arm_scmi: Fix sparse warnings in OPTEE transport driver
The sparse checker complains about converting pointers between address
spaces.  We correctly stored an __iomem pointer in struct scmi_optee_channel,
but discarded the __iomem when returning it from get_channel_shm, causing one
warning. Then we passed the non-__iomem pointer return from get_channel_shm
at two other places, where an __iomem pointer is expected, causing couple of
other warnings

Add the appropriate __iomem annotations at all places where it is missing.

optee.c:414:20: warning: incorrect type in return expression (different address spaces)
optee.c:414:20:    expected struct scmi_shared_mem *
optee.c:414:20:    got struct scmi_shared_mem [noderef] __iomem *shmem
