arm64: dts: qcom: x1e80100-*: Allocate some CMA buffers

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2078289

[ Upstream commit 50b0516030fd549c9fd4498c9ac1f3a665521b2e ]

In a fashion identical to commit 5f84c7c35d ("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.

Fixes: af16b00578 ("arm64: dts: qcom: Add base X1E80100 dtsi and the QCP dts")
Fixes: bd50b1f5b6 ("arm64: dts: qcom: x1e80100: Add Compute Reference Device")
