cdev_open() opens a cdev by name. This introduces cdev_do_open which
allows to open a cdev when the cdev is already found by other means.

currently most partition cdevs have the name <devname>.<partname>
This makes it hard to find a partition by <partname>. This introduces
a partname field in struct cdev so that.

This creates a Linux OF API compatible counterpart of of_get_named_gpio_flags.
Existing of_get_named_gpio is converted to a static inline function, which is
in the corresponding of_gpio.h include. While at it, drivers/of/gpio.c is
also renamed to drivers/of/of_gpio.c to follow the of_ prefix naming scheme.
The new include is also added to existing users of of_get_named_gpio.
