Subject: [PATCH AUTOSEL 5.5 176/542] regulator: rk808: Lower log level on optional GPIOs being not available

From: Miquel Raynal <miquel.raynal@...tlin.com>

[ Upstream commit b8a039d37792067c1a380dc710361905724b9b2f ]

RK808 can leverage a couple of GPIOs to tweak the ramp rate during DVS
(Dynamic Voltage Scaling). These GPIOs are entirely optional but a
dev_warn() appeared when cleaning this driver to use a more up-to-date
gpiod API. At least reduce the log level to 'info' as it is totally
fine to not populate these GPIO on a hardware design.

This change is trivial but it is worth not polluting the logs during
bringup phase by having real warnings and errors sorted out
correctly.
