This value shouldn't be returned from the mtd read file operation

We have fb_enable and fb_disable which handle enabling of a
framebuffer, so use it instead of calling into the ops directly.
This gets the enable count straight.

Port Linux kernel algorithm for both of_device_is_compatible() and
of_match_node(). With this change former now returns a score on the
scale of 0 to INT_MAX/2, and the latter goes through all compatiblity
entries and selects the entry that has the best matching score.
This is needed for SoCs where IP blocks are backwards compatible and
corresponding OF nodes can proclaim compatibility with several entries
found in driver's compatiblity table. One such example would be PIO
pinctrl block on AT91SAM9x5 SoCs which declare compatibility with with
both "atmel,at91sam9x5-pinctrl" and "atmel,at91rm9200-pinctrl".

The usbgadget commands uses statically allocated f_multi_opts and passes
this to usb_multi_register(). These f_multi_opts are of course no
longer valid when we leave the usbgadget command. Luckily we do not use
the data after we left the usbgadget command, so this never has been a
problem. However, f_multi_opts has some allocated members which we can
not free anymore on gadget unregistration because we no longer have the
pointer to them.
Fix this by adding a release function to struct f_multi_opts. This way
we can allocate all memory dynamically and properly free it when not
used anymore.

Depending on CONFIG_DRIVER_VIDEO_IMX_IPUV3 to decide whether to
gate IPU clocks or not is rather fragile. Any inadvertent
dependency on the IPU (like setting the NoC AQoS registers for
i.MX6QP) will result in a freeze if CONFIG_DRIVER_VIDEO_IMX_IPUV3
is disabled.

Pin number, as specified in OF pinumx entries, is relative to each bank
start, whereas both at91_mux_pin() and at91_pinctrl_set_conf() asssume
absolute pin numbering, so we need to take into account each bank's pin
base and convert pin number appropriately. Failing to do so results in
any pinmux configuration being applied to pins in bank A.
