accel: ethosu: Validate SRAM size on submit

Browse source

Regions with a BO are checked against the BO size, but the SRAM
region is not. The SRAM region doesn't have a BO, but the command stream
region size should be checked against the SRAM size. The job's
"sram_size" isn't useful here because an evil userspace could lie about
the size.
