arm64: dts: mediatek: mt8365: Describe infracfg-nao as a pure syscon

The infracfg-nao register space at 0x1020e000 has different registers
than the infracfg space at 0x10001000, and most importantly, doesn't
contain any clock controls. Therefore it shouldn't use the same
compatible used for the mt8365 infracfg clocks driver:
mediatek,mt8365-infracfg. Since it currently does, probe errors are
reported in the kernel logs:

  [    0.245959] Failed to register clk ifr_pmic_tmr: -EEXIST
  [    0.245998] clk-mt8365 1020e000.infracfg: probe with driver clk-mt8365 failed with error -17

This register space is used only as a syscon for bus control by the
power domain controller, so in order to properly describe it and fix the
errors, set its compatible to a distinct compatible used exclusively as
a syscon, drop the clock-cells, and while at it rename the node to
'syscon' following the naming convention.
