[ENHANCE] Apply the patchset for kltechn from mailing list

[Icenowy]

The GPIO I2C expander is connected differently on kltechn comparing with other kltes.

The patchset is at https://patchwork.kernel.org/project/linux-arm-msm/list/?series=825561 .

Sure, I can pick v3 https://lore.kernel.org/linux-arm-msm/[email protected]/ into the 6.7 branch (and newer) if there's interest. Otherwise with it'll also land with v6.9 or v6.10 when it gets accepted.

Well I personally wait for this to add kltechn support to pmOS (because I am in China and have kltechnduo).

Seems it's more tricky to apply this patchset on top of v6.7 but on v6.8 it applies fine. I'll include it in the 6.8 branch, it's due to be released in probably 1 week anyways since v6.7-rc7 should come out today.
