In ath79, for several SoCs the console bootargs are defined to the
very same value in every device's DTS. Consolidate these definitions
in the SoC dtsi files and drop further redundant definitions elsewhere.
The only device without any bootargs set has been OpenMesh OM5P-AC V2.
This will now inherit the setting from qca955x.dtsi
Note that while this tidies up master a lot, it might develop into a
frequent pitfall for backports.

A new shift mode was introduced since ar934x which has a way better
performance than current bitbang driver and can handle higher spi
clock properly. This commit adds a new driver to make use of this
new feature.
This new driver has chipselect properly configured and we don't need
cs-gpios hack in dts anymore. Remove them.

Important Notes
===============
0. NOR Flash (2 MiB) is not touched by OpenWrt installation.
1. NAND Flash (128 MiB) layout under OpenWrt is changed as follows:
all space is split between 4 MiB kernel and 124 MiB UBI areas;
vendor partitions (language and mtdoops) are removed; kernel space
size can be further expanded if needed; maximum image size is set
to 25600k for compatibility reasons and can also be increased.
2. CPU clock is 775 MHz, not 750 MHz.
3. 5 GHz wireless radio chip is Atheros AR9580-AR1A with bogus PCI
device ID 0xabcd. For ath9k driver to load successfully, this is
overriden in DTS with correct value for this chip, 0x0033.
4. RFKILL button is wired to AR9580 pin 9 which is normally disabled
by chip definition in ath9k code (0x0000F4FF gpio mask). Therefore
'qca,gpio-mask=<0xf6ff>' hack must be used for button to work
properly.
5. USB port is always on, no GPIO for 5V power control has been
identified.
Installation
============
* TFTP recovery
* TFTP via U-boot prompt
* sysupgrade
* Web interface
