Subject: [PATCH] riscv: Kconfig.errata: Drop dependency for MMU in ERRATA_ANDES_CMO config

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Now that RISCV_DMA_NONCOHERENT conditionally selects DMA_DIRECT_REMAP
ie only if MMU is enabled, we no longer need the MMU dependency in
ERRATA_ANDES_CMO config.

Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Note, this patch needs to be applied only if patch [1] is accepted or else
we might see build issues with randconfig.
