regulator: max20086: Fix MAX200086 chip id

commit 71406b6d1155d883c80c1b4405939a52f723aa05 upstream.

>From MAX20086-MAX20089 datasheet, the id for a MAX20086 is 0x30 and not
0x40. With the current code, the driver will fail on probe when the
driver tries to identify the chip id from a MAX20086 device over I2C.
