[PATCH] driver: nand: skip BBT scan during SPL to reduce size and complexity

[dinesh.maniyam at altera.com]

From: Dinesh Maniyam <dinesh.maniyam at altera.com>

Guard the Bad Block Table (BBT) scanning with `#ifndef CONFIG_SPL_BUILD`
to prevent running `chip->scan_bbt()` in SPL builds.

The SPL only requires basic NAND read functionality to load the next
stage and does not need full BBT management. Running the BBT scan in
SPL unnecessarily increases code size, memory usage, and boot time.

This change ensures the BBT is scanned only in U-Boot proper, where the
full NAND subsystem and dynamic memory are available.
