The mcp2221_raw_event retrieves the value and direction of gpio on the
same command, by setting the value on mcp->status and the direction on
mcp->gpio_dir; and the offset at which they are read is based on
mcp->gp_idx, set by the gpiochip callbacks.
However, the individual gpiochip calls set the index to look for
directly on the field they want to track. This create a "double offset"
in the final read in the response report.
Align the behaviour of mcp2221_raw_event and
mcp_gpio_get/mcp_gpio_get_direction by putting gp_idx on those calls to
the base offset of the gpio status struct.
