introducing the devices, vdda-phy(~0.9v) first and vdda-pll(1.2v)
later in the upstream while vdd(0.912v) first and core(1.2v) later in
the downstream. BTW, the DSDT is unreliable. On my platform, it
describes that several components are consuming several LDOs, but
these components work well with these LDOs manually disabled via rpmh.
