msm: ipa3: Validate IPA and GSI firmwares before loading
IPA and GSI firmwares are saved on the file-system as an
ELF file. IPA driver extracts the firmwares and load
them during driver initialization.
This change adds validation steps to each firmware before
loading: load addresses, memory sizes, firmware sizes and
more...
