soc/intel/common/block: fix storage size of HEST log address

This patch fixes the storage size to reflect the proper bits instead
of bytes. It was a bug in the initial HEST patch
(https://review.coreboot.org/c/coreboot/+/52090), and commit ID d4db36e672644ac7f528d12c5ce3539725456085 . Also fixed the
comments to properly reflect the range being used.
