gpio: mxs: Get rid of external API call
[ Upstream commit 833eacc7b5913da9896bacd30db7d490aa777868 ]
The MXS driver was calling back into the GPIO API from
its irqchip. This is not very elegant, as we are a driver,
let's just shortcut back into the gpio_chip .get() function
instead.
This is a tricky case since the .get() callback is not in
this file, instead assigned by bgpio_init(). Calling the
function direcly in the gpio_chip is however the lesser
evil.
