Bump up MAX_HWCNT and MAX_EXCNT to 32 when ACPI is enabled. These are the sizes of the hwregions and exregions arrays respectively. ACPI firmware typically has more memory regions and the current value of 16 is not sufficient for some platforms. This commit fixes a failure seen with AMI firmware on Cavium's Sabre ThunderX2 reference platform. This platform needs 21 physical memory regions and 18 excluded regions to boot correctly with the current firmware release.
