soc: fsl: qe: request pins non-exclusively
Commit 84582f9ed0 ("soc: fsl: qe: Avoid using gpio_to_desc()") changed
qe_pin_request() to request and hold GPIO corresponding to a given pin.
Unfortunately this does not work, as fhci-hcd requests these GPIOs
first, befor calling qe_pin_request() (see
drivers/usb/host/fhci-hcd.c::of_fhci_probe()).
To fix it change qe_pin_request() to request GPIOs non-exclusively, and
free them once the code determines GPIO controller and offset for each
GPIO/pin.

Also reaching deep into gpiolib implementation is not the best idea. We
should either export gpio_chip_hwgpio() or keep converting to the global
gpio numbers space until we fix the driver to implement proper pin
control.
