6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Fitzgerald rf@opensource.cirrus.com
commit 18789be8e0d9fbb78b2290dcf93f500726ed19f0 upstream.
Do not allow the CS35L56 to be put into its lowest power "hibernation" mode. This only affects I2C because "hibernation" is already disabled on SPI and SoundWire.
Recent firmwares need a different wake-up sequence. Until that sequence has been specified, the chip "hibernation" mode must be disabled otherwise it can intermittently fail to wake.
Backport note: This is the same change as upstream commit, to delete one line, but the upstream commit would not apply cleanly on older branches because of minor differences to the surrounding code.
