Subject: [PATCH v2 3/3] arm64: dts: mediatek: mt8173-elm: drop PMIC's syscon node

According to AngeloGioacchino Del Regno, the syscon node in PMIC is
neither needed nor used.  It looks like a solution to expose some of the
registers of PMIC.

Drop it to solve also incorrect number of entries in the "reg" property
and fix dtbs_check warning:

  mt8173-elm.dtb: syscon@...0: reg: [[0, 49152], [0, 264]] is too long

Changes in v2:
1. Drop the node as suggested.
