Select CONFIG_64BIT so that we pass the -m64 option (instead of -m32) to static analysis tools. Introduce CONFIG_SPL_64BIT and select it for architectures other than x86 with 64 bit builds. Do not select it for x86 builds as x86 uses a 32 bit SPL. Ensure that when limits are set they use CONFIG_64BIT for U-Boot proper and CONFIG_SPL_64BIT for SPL. This is to allow for the 32 bit SPL build used by x86.

Changes in v4: - Add help text to describe new symbol CONFIG_SPL_64BIT - Splite statement in bloblist.c to make it more readable
Changes in v3: Introduce CONFIG_SPL_64BIT to allow for x86 building a 32 bit SPL and a 64 bit U-Boot proper.
Changes in v2: Corrected commit title to be x86 not sandbox
