soc/intel/adl: Cast size in systemagent.c to fix overflow
This CL fixes my previous CL (commit ca741055e)
which introduced a couple of issues found by Coverity (see below).
The Coverity explanation is: "Potentially overflowing expression "size_field * 1048576U" with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "uint64_t" (64 bits, unsigned)."
*** CID 1490122: Integer handling issues (OVERFLOW_BEFORE_WIDEN)
/src/soc/intel/alderlake/systemagent.c: 305 in get_dpr_size()
*** CID 1490121: Integer handling issues (OVERFLOW_BEFORE_WIDEN)
/src/soc/intel/alderlake/systemagent.c: 254 in get_dsm_size()
