mfd: rk808: Fix RK818 ID template
[ Upstream commit 37ef8c2c15bdc1322b160e38986c187de2b877b2 ] 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.
