uboot-at91: fix build failure with GCC 14.4

It seems that GCC 14.4 will generate larger binary compared to the
GCC 14.3 on ARM32 platforms. We have to increase the maximum allowed
SPL size to fix build errors.

+Subject: [PATCH] increase max SPL size
+
+The GCC 14.4 generates slightly larger binaries for the Cortex-A5
+platform. This resulted in the build failure on some emmc based
+boards. Fix it by increasing the CONFIG_SPL_MAX_SIZE.
