[U-Boot] [PATCH v2] fdt_support: Use VLA instead of MEMORY_BANKS_MAX

[Ramon Fried <ramon.fried@gmail.com>]

Instead of relaying on user to configure MEMORY_BANKS_MAX
correctly, use VLA (variable length array) to accommodate the
required banks.

Fixes: 2a1f4f1758b5 ("Revert "fdt_support: Use CONFIG_NR_DRAM_BANKS if
defined"")
