arm64: dts: qcom: sdm845-akatsuki: Round down l22a regulator voltage

Browse source 
[ Upstream commit 4148a9eeb1 ]

2700000 is not a multiple of pmic4_pldo's step size of 8000 (with base
voltage 1664000), resulting in pm8998-rpmh-regulators not probing.  Just
as we did with MSM8998's Sony Yoshino Poplar [1], round the voltages
down to err on the cautious side and leave a comment in place to
document this discrepancy wrt downstream sources.
