Subject: [PATCH] lsslot: Fix lsslot -c mem output when using 4GB LMB size

Upstream: Expected v1.3.11
Git-commit: b1b9e76de0f3ab1dfcd9426779fa20fd77cd5625

When using a LMB size of 4GB, the output of lsslot -c mem would get
reported incorrectly as:

Dynamic Reconfiguration Memory (LMB size 0x0)
:
    DRC Index: 80000001        Address: 100000000
    Removable: No              Associativity: (index: 1) 0 1 4 9
    Section(s):

This patch changes the declaration of the _node_u._smem._lmb_size from
a uint32_t to uint64_t to store the value properly. Any variables that
store the lmb_size are also declared as uint64_t. In addition, we
use the PRIx64 macro in printf statements to properly print the
lmb_size value.

The patch also includes a necessary change to declare the global
variable block_sz_bytes as a uint64_t to fix an infinite loop in
the function get_mem_scns() when the above changes were introduced.
