Hugo Villeneuve 24ea2c4d48 serial: max310x: prevent infinite while() loop in port startup ...

commit b35f8dbbce818b02c730dc85133dc7754266e084 upstream.

If there is a problem after resetting a port, the do/while() loop that
checks the default value of DIVLSB register may run forever and spam the
I2C bus.

Add a delay before each read of DIVLSB, and a maximum number of tries to
prevent that situation from happening.

Also fail probe if port reset is unsuccessful.
