[PATCH v1] configs: microchip_mpfs_icicle: disable DEBUG_UART

From: Conor Dooley <conor.dooley at microchip.com>

By default DEBUG_UART uses the SBI DBCN extension on S-Mode RISC-V
platforms, but the Icicle Kit's firmware doesn't support it. Since
DEBUG_UART is getting turned on automagically and this is somewhat
misleading, disable it in the Icicle kit's defconfig.
