[PATCH RESEND 1/5] ARM: dts: clps711x: Add SYSCON nodes where it is used

[Alexander Shiyan]

This patch adds SYSCON descriptors to framebuffer, SPI, DAI
and modem control GPIO nodes to further rework these drivers
to remove the call to the syscon_regmap_lookup_by_compatible() function.

[PATCH RESEND 5/5] ARM: dts: clps711x: Add an empty chosen node to top level DTSI

[Alexander Shiyan]

Missing "chosen" node can cause issues when booting a kernel
with a boot-loader that doesn't create a chosen node if this
isn't present in the DTB since the decompressor relies on a
pre-existing chosen node to be available to insert the command
line and merge other ATAGS info.
