[PATCH v2 1/5] arch: arm: dts: cpcap-mapphone: Set VAUDIO regulator always-on

VAUDIO regulator is used by cpcap codec and currently is enabled/disabled
by dapm logic, however, when regulator is turned off, various cpcap
functions (like jack detection) do not work.

Configure VAUDIO regulator-allowed-modes property while at it to enable
low-power regulator mode being set.
