The HLCDC IP available in some Atmel SoCs (i.e. sam9x5i.e. at91sam9n12,
at91sam9x5 family or sama5d3 family) provide a PWM device.
This driver add support for a PWM chip exposing a single PWM device (which
will most likely be used to drive a backlight device).

Since non-DT board support has been removed from the at91 architecture we
can safely remove non-DT handling code.

Peripheral clock is named pclk and system clock is named hclk (those are
the names expected by the at91_udc driver).
Drop the deprecated usb_clk (formerly used to configure the usb clock rate
which is now directly configurable through hclk).

The driver is requesting clock by their global name (those declared in the
clk_lookup list), but this only works with !CCF kernels.
Now that all SoCs have moved to CCF, fix the driver to use local names
(hclk and pclk).

Now that at91 system clocks forward set_rate request to their parent we
can remove the uclk clock and directly call clk_set_rate on fclk.

The at91_udc driver request 2 clocks, and thus need them to be defined in
the device tree.
Document the clocks and clock-names properties so that everybody use the
correct names.

- drop AT91_EBICSA_REGFIELD and AT91_MULTI_EBICSA_REGFIELD macros
Changes since v2:
- minor fixes int DT bindings doc
- fix SMC macros
- make use of SMC macros defined in include/linux/mfd/syscon/atmel-smc.h
Changes since v1:
- almost everything :-)

For specific device controllers (like the NAND one) the SMC timings
