southbridge/intel: Update top swap block size using ifdtool option

Currently the INTEL_TOP_SWAP_BOOTBLOCK_SIZE is used in the context of
cbfstool/ifittool to add top swap boot block and update fit pointers. The
top-swap size definition is in 2 places i.e., descriptor and Kconfig,
which will have to be aligned by the developer and can be missed.
To address this issue, use the option (-j) added in ifdtool to set the
top-swap size to whatever value is specified by INTEL_TOP_SWAP_BOOTBLOCK_SIZE.

When INTEL_TOP_SWAP_BOOTBLOCK_SIZE=0x10000,
