disk: make get_partition_info() always available to disk.c
Now that get_device_and_partition() always calls get_partition_info() when disk.c is compiled, we must always compile the function, rather than ifdef it away. The implementation must be conditional based on CONFIG_CMD_* etc., since that's what e.g. part_dos.c uses to ifdef out get_partition_info_dos(); CONFIG_DOS_PARTITION can be enabled even without those commands being enabled. Technically, this change is required before Rob's "disk/part: introduce get_device_and_partition" patch. However, at least when the compiler optimizer is turned on, it isn't required before then in practice, since get_device_and_partition() calls get_dev(), which is stubbed out in disk.c under exactly the same conditions that get_partition_info() is not compiled, and hence the compiler never generates code for the call to the missing function. However, in my later patch "disk: get_device_and_partition() "auto" partition and cleanup", the optimizer doesn't succeed at this, and may attempt to reference the undefined function.
