This is to prepare for Milkv Mars board dts support in the following
patch. Let's factored out common part into .dtsi.

This partially reverts
commit 92cfc35838b2 ("riscv: dts: starfive: Add the nodes and pins of I2Srx/I2Stx0/I2Stx1")
This added device tree nodes for I2S hardware that is not actually on the
VisionFive 2 board, but connected on the 40pin header. Many different extension
boards could be added on those pins, so this should be handled by overlays
instead.
This also conflicts with the TDM node which also attempts to grab GPIO 44:
starfive-jh7110-sys-pinctrl 13040000.pinctrl: pin GPIO44 already requested by 10090000.tdm; cannot claim for 120c0000.i2s

Interrupt line number of the AXP15060 PMIC is not a necessary part of
its device tree. Originally the binding required one, so the dts patch
added an invalid interrupt that the driver ignored (0) as the interrupt
line of the PMIC is not actually connected on this platform. This went
unnoticed during review as it would have been a valid interrupt for a
GPIO controller, but it is not for the PLIC. The PLIC, on this platform
at least, silently ignores the enablement of interrupt 0. Bo Gan is
running a modified version of OpenSBI that faults if writes are done to
reserved fields, so their kernel runs into problems.
Delete the invalid interrupt from the device tree.

StarFive:
Things are a bit slower for StarFive this window, there's only the
addition of audio related DT nodes to speak of here.
Generic:
The SiFive, StarFive and Microchip devicetrees have had my replacement
ISA extension detection properties added. Unfortunately, the old
"riscv,isa" property never defined exactly what the extensions it
contained meant, and people were want to fill it in incorrectly (and
call upstream kernel devs idiots for not doing the same). The new
properties have explicit definitions and hopefully will stand up better
to some of the variation from RVI.
Sophgo:
Two new SoCs, one is probably the first of several with up/down tuned
variants, that have a pair of T-Head c906 cores and appear aimed at the
IP camera, smart <insert whatever> etc markets. They are intended to run
in AMP mode, with an RTOS on the less powerful core. The other is far
more interesting to kernel developers however, the 64-core SG2042, with
more recent c920 cores from T-Head at 2 GHz. For both, support is at a
very basic stage - some of the same developers are working on them as
other T-Head powered SoCs, but hopefully things will move beyond a basic
console boot. The goal is for Chen Wang to take over maintaining the
Sophgo support once they have some more experience with the process.

The Starfive VisionFive 2 has a 16MiB NOR flash, while the reserved-data
partition is declared starting at address 0x600000 with a size of
0x1000000. This causes the kernel to output the following warning:
[ 22.156589] mtd: partition "reserved-data" extends beyond the end of device "13010000.spi.0" -- size truncated to 0xa00000
It seems to be a confusion between the size of the partition and the end
address. Fix that by specifying the right size.
