libpayload: Add CBMEM_IMD_ENTRY support to coreboot tables parser

coreboot stores much information in the CBMEM IMD. Until now it was
ignored. This patch makes use of these coreboot tables entries.
It also removes get_cbmem_addr() function as it is no longer needed.

Moreover, the coreboot tables entry CB_TAG_MRC_CACHE does not exist
anymore, as it is not created by the code. It was replaced by
CBMEM_ID_MRCDATA entry, so MRCDATA should now be accessible through
sysinfo structure field.
