[PATCH 5.3 077/344] gpio: madera: Add support for Cirrus Logic CS47L92

[Greg Kroah-Hartman]

From: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxx>

[ Upstream commit 74d2d0e68701bcd53d2cf771dd3b3cb9f84bed5c ]

As the gpio is common to all madera codecs all that is needed
is to setup the correct number of GPIO pins for the CS47L92.
