Subject: [PATCH 4.19 185/191] ARM: s3c24xx: fix missing system reset

From: Krzysztof Kozlowski <krzk@...nel.org>

commit f6d7cde84f6c5551586c8b9b68d70f8e6dc9a000 upstream.

Commit f6361c6b3880 ("ARM: S3C24XX: remove separate restart code")
removed usage of the watchdog reset platform code in favor of the
Samsung SoC watchdog driver.  However the latter was not selected thus
S3C24xx platforms lost reset abilities.
