hwmon: (pmbus/max8688) Accept negative page register values
A negative page register value means that no page needs to be selected. This is used by status register evaluations and needs to be accepted. Fixes: da8e48ab483e1 ("hwmon: (pmbus) Always call _pmbus_read_byte in core driver") Signed-off-by: Guenter Roeck <linux@roeck-us.net>
