Subject: [PATCH v4] mfd: intel-lpss: Add missing PCI ID for Intel Sunrise Point LPSS devices

This patch adds a missing PCI ID of the Intel Sunrise Point chipset to the Intel LPSS driver.
It fixes a bug causing the touchpad of the Lenovo Yoga 720-15 not to be recognized.
See also bug 1700657 on bugs.launchpad.net.
