QCLINUX: arm64: dts: qcom: Add shared X1 staging overlay

[jiegan0107]

Move the common Hamoa staging overlay contents into x1-staging.dtsi so they can be shared across X1 platforms. Keep hamoa-staging.dtso as a thin wrapper around the shared include and add purwa-staging.dtso to build an identical staging overlay for Purwa.
