SCCR map for multi-chip devices contains the number of additional dice in the device and register offset values for each additional dice. spi_nor_parse_sccr_mc() is added to determine the number of dice and volatile register offset for each die. The volatile register offset table may already be allocated and contains offset value for die-0 via SCCR map parse. So, we should use devm_krealloc() to expand the table with preserving die-0 offset.
