soc: qcom: add secure processor subsystem (spss) utils driver

Browse source 
The spss-util driver provides utilities required for the Secure
Processor Subsystem (SPSS). It provides the fuse state for key selection
and the SPSS HW version.

Add snapshot for spss-util driver from msm-4.19 commit a7793b40172f
("soc: qcom: spss_utils: fix spss SSR when IAR not active").

spss-utils driver selects Secure Processor firmware file name.name
The firmware file name for dev, test or production is selected
based on two fuses.fuses
Different file name is used for differnt SPSS HW versions,versions
because the SPSS firmware size is too small to support multiple
