7b74b40fe9 ipq806x: remove "firmware" partition definition from netgear routers
Remove the "firmware" partition definition from the DTS of R7800
to fix sysupgrade.

Commit 4645a6d3 defined CONFIG_MTD_SPLIT_UIMAGE_FW=y for ipq806x
and that causes mtd to misbehave as additional kernel and ubi
partitions are detected from inside the "firmware" partition.
  [    1.111324] 0x000001480000-0x000001880000 : "kernel"
  [    1.121005] 0x000001880000-0x000007900000 : "ubi"
  [    1.283912] 0x000007900000-0x000008000000 : "reserve"
  [    1.296407] 0x000001480000-0x000007900000 : "firmware"
  [    1.468043] no rootfs found after FIT image in "firmware"
  [    2.426860] 2 uimage-fw partitions found on MTD device firmware
  [    2.426931] 0x000001480000-0x000001880000 : "kernel"
  [    2.440420] 0x000001880000-0x000007900000 : "ubi"

Both kernel and ubi are already defined in DTS, so this duplication
leads into errors in sysupgrade:
  Writing from <stdin> to kernel ...
  ubiattach: error!: strtoul: unable to parse the number '6 mtd10'
  ubiattach: error!: bad MTD device number: "6 mtd10"

The partition is defined to same area as kernel+ubi, and is not
needed for sysupgrade anymore. Remove it to fix things.

Only tested for the R7800 but all of them should behave equal.

Fixes: FS#1617

fb8a578aa7 ipq806x: Enlarge R7800 flash - use netgear partition
Increase the available flash memory size in Netgear R7800
by taking into the use the unused "netgear" partition
that is located after the firmware partition.

Available flash space for kernel+rootfs+overlay increases
by 68 MB from 32 MB to 100 MB.

In a typical build, overlay space increases from 15 to 85,
increasing the package installation possibilities greatly.

Reverting to the OEM firmware is still possible, as the OEM
firmware contains logic to initialise the "netgear" partition
if its contents do not match expectations. In OEM firmware,
"netgear" contains 6 UBI sub-partitions that are defined in
/etc/netgear.cfg and initialisation is done by /etc/preinit

Tested with Openwrt master r7093-4fdc6ca31b and OEM V1.0.2.52

96cd31655d ipq806x: remove rpm pinctrl from board dts
These pins seem to be used by hw exclusively, so claiming it in
kernel causes an error in syslog in k4.14+.

> socinfo_init: v6, id=280, ver=3.0, raw_id=17, raw_ver=17, hw_plat=0,  hw_plat_ver=65536

Include dtsi accordingly and remove the unneeded qcom-ipq8065-v1.0.dtsi

dc50694bd1 ipq806x: increase kernel partition size for the Netgear r7800
Starting with kernel 4.14 and gcc 7, the kernel doesn't fit into the
2 MB reserved for the kernel partition by the OEM firmware anymore.

This patch increases the kernel partition from 2 MB to 4 MB, at the
expense of the rootfs, for all supported kernels.

WARNING: This breaks sysupgrade! Flashing a firmware containing this
changed partitioning from an older image with 2 MB reserved for the
kernel partion requires the tftp recovery procedure, thereby losing
all settings.

This patch is based on a corresponding change by Pavel Kubelun
<be.dissent@gmail.com> and has been tested by Michael Yartys
<michael.yartys@protonmail.com>

- Rebased the patches for 4.14
 - Dropped spi-qup and 0027, 0028, 0029
   clk patches since it's already included
   in upstream.

 Tested on IPQ AP148 Board:
  1) NOR boot and NAND boot
  2) Tested USB and PCIe interfaces
  3) WDOG test
  4) cpu frequency scaling
  5) ethernet, 2G and 5G WiFi
  6) ubi sysupgrade
