Refactor Aspeed kernel-6.12 v00.07.02 update patch

[roger-nexthop]

Why I did it

Based on community feedback, this PR restores the original aspeed-ast2700-support.patch merged in #522. The update to kernel-6.12 v00.07.02 (#557) has been split into 2 patches based on aspeed specific changes and vendor independent changes.

The two new patches for 00.07.02 update will be applied as incremental patches on top of the original Aspeed kernel patch.

How I did it

Restored original aspeed patch. Split 00.07.02 update into two patches based on new aspeed files and modified aspeed/vendor independent files.

How to verify it

Tested by running new image with the changes and checking patched kernel is same before and after this change.

Renamed files for clarity (new aspeed files versus modifications to existing aspeed + vendor independent) and numbered as suggested.

LGTM. @roger-nexthop did you use the Linux kernel repo PR template?

sonic-linux-kernel is missing the PULL_REQUEST_TEMPLATE.md, but I've updated this based on sonic-buildimage.

Comments:

• In the first patch, in drivers/clk/Kconfig and drivers/clk/Makefile, there is a new kconfig named CONFIG_COMMON_CLK_NPCM8XX that gets defined with a reference to a new file named clk-npcm8xx.c. However, this does not exist in the patch or in the 6.12.94 source tree.
• In the first patch, in drivers/char/hw_random/Kconfig, HW_RANDOM_NOMADIK has a depends on ARM_AMBA added.
• In the first patch, in drivers/irqchip/Makefile, it looks like the build rule for CONFIG_STM32MP_EXTI was removed.
• I see the above three changes were reverted in the third patch. Any way they can be removed from both the first and third patch?
  • drivers/reset/Kconfig might also apply to this category
• In the third patch, there's a change to drivers/edac/synopsys_edac.c. Is this expected?

Thanks Saikrishna for the review. I've cleaned up the first and third patches as suggested. synopsys_edac.c was also unnecessarily modified due to the different baseline in the first patch and it came back to original state in the 3rd patch.
