[U-Boot] [PATCH V3 1/8] disk: parameterize get_device_and_partition's loop count

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Create #define MAX_SEARCH_PARTITIONS to indicate how many partition IDs
get_device_and_partition()'s automatic mode should search through. Also,
search 1..n not 1..n-1 - it's unlikely anyone has this many partitions,
but given the loop is 1-based, including the limit seems more consistent.
