soc/intel: Fix pointer size mismatch errors in crashlog
The crashlog code in intel/common/block and meteorlake soc
was casting integer addresses directly to pointer types,
which caused compilation errors in x86_64 bit builds.
This commit fixes the issue by using uintptr_t for casting
integer addresses to pointer types before dereferencing.
BUG=b:329034258
TEST=Successfully build Meteor Lake (rex) in both x86_32 and
x86_64 modes.
