xip_customize: Four fixes for relieving Seeprom space constraint.
1) Now calculating correct value of MAX_SEEPROM_IMAGE_SIZE.
2) Now returning error RC!=0 whenever image size exceeds Seeprom space.
3) Now allowing for temporarily exceeding max image size during
customization of Vpd rings since we know with certain that the
image will loose three sections (toc, fixed_toc and strings) as
the very last step in xip_customize.
4) Now extracting platform dependent value of MAX_SBE_SEEPROM_SIZE
to allow Cronus to use larger image size than can fit into SBE
Seeprom.
5) Updated wrapper as well to illustrate the new rule how to call
xip_customize, namely by supplying buffer sizes greater than
MAX_SEEPROM_IMAGE_SIZE, e.g. using MAX_SBE_SEEPROM_SIZE instead.
Please see xip_customize.H for new API rules.
