[PATCH] arm64: versal2: Initialize num_banks variable in dram_init()

In dram_init() num_banks is incremented for every detected DRAM bank
and passed to mem_map_fill() without being initialized, which can add
invalid entries to versal2_mem_map[], so initialize it to zero.

Fixes: 3aebac5a759b ("arm64: versal2: Populate DRAM banks before page table size calculation")
