Chen-Yu Tsai 5b8d3ea093 regulator: mt6358: Fail probe on unknown chip ID 
[ Upstream commit 7442edec72bc657e6ce38ae01de9f10e55decfaa ]

The MT6358 and MT6366 PMICs, and likely many others from MediaTek, have
a chip ID register, making the chip semi-discoverable.

The driver currently supports two PMICs and expects to be probed on one
or the other. It does not account for incorrect mfd driver entries or
device trees. While these should not happen, if they do, it could be
catastrophic for the device. The driver should be sure the hardware is
what it expects.

Make the driver fail to probe if the chip ID presented is not a known
one.
