[PATCH RESEND] mfd: rk808: Fix RK818 ID template

From: Heiko Stuebner
Date: Mon May 13 2019 - 04:31:52 EST

From: Daniel Schultz <d.schultz@xxxxxxxxx>

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.

The original patch from Feburary 2018 got an Ack but never reached
the mfd-tree, so I ran into that problem this weekend as well.
So it would be really cool if this could be applied as fix :-) .
