cpu/x86/mtrr: fix OVERFLOW_BEFORE_WIDEN
Integer handling issues: Potentially overflowing expression "1 << size_msb" with type "int" (32 bits, signed) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "uint64_t" (64 bits, unsigned). Fixes: CID 1435825 and 1435826 Signed-off-by: Jonathan Zhang <jonzhang@fb.com> Change-Id: If859521b44d9ec3ea744c751501b75d24e3b69e8 Reviewed-on: https://review.coreboot.org/c/coreboot/+/46711 Reviewed-by: Marc Jones <marc@marcjonesconsulting.com> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
