ITP loading
This adds functionality to load and execute ITP in an early stage just after eMMC init.
eMMC init was moved to mmc_host.c since it fits better there and is needed in
order to access ITP before loading env.
Flag for functionality is CONFIG_ITP_LOAD.
This functionailty depends on CONFIG_TOC_PARTITION
