In a fashion identical to commit 5f84c7c35d49 ("arm64: dts: qcom: sc8280xp: Define CMA region for CRD and X13s"), there exists a need for more than the default 32 MiB of CMA, namely for the ath12k_pci device. Reserve a 128MiB chunk to make boot-time failures like: cma: cma_alloc: reserved: alloc failed, req-size: 128 pages, ret: -12 go away.
