arm: k3: config.mk: Read software revision information from file on HS

Browse source 
Read the swrv.txt file from the TI Security Development Tools when
TI_SECURE_DEVICE is enabled. This allows us to set our software
revision in one place and have it used by all the tools that create
TI x509 boot certificates.
