cpu/x86/smm: Fix size_t type mismatch in print statement
The 64-bit compiler x86_64-linux-gnu-gcc-10 aborts the build with the format warning below: CC ramstage/cpu/x86/smm/smm_module_loader.o src/cpu/x86/smm/smm_module_loader.c: In function 'smm_module_setup_stub': src/cpu/x86/smm/smm_module_loader.c:360:70: error: format '%lx' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Werror=format=] 360 | printk(BIOS_ERR, "%s: state save size: %zx : smm_entry_offset -> %lx\n", | ~~^ | | | long unsigned int | %x As `size_t` is defined as `long unsigned int` in i386-elf (32-bit), the length modifier `l` matches there. With x86_64-elf/x86_64-linux-gnu (64-bit) and `-m32` `size_t` is defined as `unsigned int` resulting in a type mismatch. So, use the correct length modifier `z` for the type `size_t`.
