commit 37ef8c2c15bdc1322b160e38986c187de2b877b2 upstream.
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.
Fixes: 9d6105e19f61 ("mfd: rk808: Fix up the chip id get failed")
