Subject: [PATCH AUTOSEL 5.10 14/50] bus: ti-sysc: Use context lost quirks for gpmc

From: Tony Lindgren <tony@...mide.com>

[ Upstream commit d48dca51935b8ca13356e726442c21ec94668d69 ]

At least on am335x, the gpmc module needs a re-init and reset if context
has been lost on resume. We can enable this for all gpmc revisions as we
check if the context was lost before restoring it.
