Subject: [RFC PATCH 2/2] arm64: dts: renesas: ulcb-kf: adapt sound 5v regulator to schematics

Sound uses the standard 5V supply, so rename the fixed regulator as
such. Also add properties dcoumenting it is always on, also during boot.

Signed-off-by: Wolfram Sang <wsa+renesas@...g-engineering.com>

Or shall we move the regulator to ulcb.dtsi? I tend to leave it here
because 5V are not used on ULCB, but I am open to change it.
