[coreboot] [flashrom] layout.c: couple of nitpicks

[Andriy Gapon]

It seems that in show_id() type of 'walk' variable should of fixed size 
(i.e. uint32_t) for x86_64 portability.

Also, it looks suspicious that two legacy bios checks (nvidia and 
general) are exactly the same:
if ((*walk) == 0 || ((*walk) & 0x3ff) != 0) {
         /* We might have an Nvidia chipset bios
...
}

if ((*walk) == 0 || ((*walk) & 0x3ff) != 0) {
         printf("Flash image seems to be a legacy BIOS. Disabling 
checks.\n");
...
