storage: 64-bit sector offsets

 * Create new 'sector_t' type alias:
    * uint64_t for all targets with HAVE_LBA48 or HAVE_SDUC
    * unsigned long for the everything else
 * Alter all storage APIs to use sector_t instead of 'unsigned long'
 * Alter Volume/Partition/storage info structures to use sector_t
 * Disk cache converted to sector_t
 * ATA Core:
    * convert to using sector_t for sector addresses and drive sizes
    * Always fill out upper 16 bits of LBA48 addresses
    * IDENTIFY INFO is fixed at 512 bytes, not SECTOR_SIZE
 * USB mass storage:
    * convert to using sector_t for sector addesses and drive sizes
    * Implement READ_16/WRITE_16 for LBA48 addresses
 * Convert FAT code to use sector_t for all sector references
 * output_dyn_value() now accepts int64_t instead of 'int'
 * Corrected "rockbox info" to work for (MULTIVOLUME & !MULTIDRIVE)
 * Better reporting of disk and (logical+physical) sector sizes in debug info
 * Detect SDUC cards and report on storage debug_info screen

To-do: SDUC

 * Refactor SD core to remove duplicate code in every driver
   * Card probe and init state machine
 * Implement core SDUC support
   * SD2.0 needs to be 2.0+ (fixed for jz47xx and x1000)
   * Host and Card ID (ACMD41)
   * 32-bit addressing for all read/write/erase operations (CMD22)
 * ADD SDUC to target device drivers, defining HAVE_SDUC as appropriate
