On LS1, DDR is initialized by reading SPD through I2C interface in SPL code. For I2C, ll_entry_count() is called, and it returns the number of elements of a linker-generated array placed into subsection of .u_boot_list section specified by _list argument. So add I2C linker list in the generic .lds to fix the issue about using I2C in SPL.
