[PATCH v2] configs: am65x_evm_r5_usbdfu_defconfig: Fix USB DFU boot

[Hrushikesh Salunke]

Increase the size of malloc region allocated before relocation, as
current size is insufficient for DFU boot causing it to overflow and
corrupt the stack.

Fixed regulator configs are required by vtt_supply which is used by
"am654_ddrss" driver. Without it during DFU boot DDRSS initialization
is failing. These configs are enabled in "am65x_evm_r5_defconfig" but
are missing from "am65x_evm_r5_usbdfu_defconfig". Fix that by updating
"am65x_evm_r5_usbdfu_defconfig" to include "am65x_evm_r5_defconfig".

This patch is based on following commit in master branch
57bbc4de75f Merge tag 'qcom-fixes-2025.04-rc4' of https://source.denx.de/u-boot/custodians/u-boot-snapdragon

Changes since v1
Instead of directly adding required configs to "am65x_evm_r5_usbdfu_defconfig",
updated it to include "am65x_evm_r5_defconfig".
