[E][F][SRU][PATCH 1/1] UBUNTU: SAUCE: mfd: rk808: Fix RK818 ID template

[Po-Hsu Lin]

From: Daniel Schultz <d.schultz at phytec.de>

BugLink: https://bugs.launchpad.net/bugs/1853192

The Rockchip PMIC driver can automatically detect connected component
versions by reading the ID_MSB and ID_LSB registers. The probe function
will always fail with RK818 PMICs because the ID_MSK is 0xFFF0 and the
RK818 template ID is 0x8181.

This patch changes this value to 0x8180.
