brcm63xx: add kernel 4.9 support

Add support for kernel 4.9 based on the more upstream comformant
partition defintions. Increases compressed kernel size by ~95k
compared to 4.4.

+
+Consider a message size limit when calculating the maximum amount
+of data that can be read.
+
+The message size limit has been introduced with 4.9, so cc it
+to stable.

+Subject: [PATCH 2/8] spi/bcm63xx: make spi subsystem aware of message size
+ limits
+
+The bcm63xx LS SPI controller does not allow manual control of the CS
+lines and will toggle it automatically before after sending data, so we
+are limited to messages that fit in the FIFO buffer. Since the CS lines
+aren't available as GPIOs either, we will need to make slave drivers
+aware of this limitation and handle it accordingly.

++Binding for Broadcom BCM6348/BCM6358 SPI controller
++
++Required properties:
++- compatible: must contain one of "brcm,bcm6348-spi", "brcm,bcm6358-spi".
++- reg: Base address and size of the controllers memory area.
++- interrupts: Interrupt for the SPI block.
++- clocks: phandle of the SPI clock.
++- clock-names: has to be "spi".
++- #address-cells: <1>, as required by generic SPI binding.
++- #size-cells: <0>, also as required by generic SPI binding.
++
++Optional properties:
++- num-cs: some controllers have less than 8 cs signals. Defaults to 8
++  if absent.
++
++Child nodes as per the generic SPI binding.
++
++Example:
++
++	spi@10000800 {
++		compatible = "brcm,bcm6368-spi", "brcm,bcm6358-spi";
++		reg = <0x10000800 0x70c>;
++
++		interrupts = <1>;
++
++		clocks = <&clkctl 9>;
++		clock-names = "spi";
++
++		num-cs = <5>;
++

++		#size-cells = <0>;
++	};
