PM8009 was erroneously added since this device doesn't actually have it.
It triggers a big critical error at boot, so we're drop it.

Also it looks like the fuel gauge is not connected to the battery,
it reports nonsense info. Downstream kernel uses pmic fg.

PMIC fuel-gauge driver uses mixed stats about dual-cell battery,
so I combined it into one.

Fixes: 264beb3cbd0d ("arm64: dts: qcom: sm8250-xiaomi-pipa: Add initial device tree")

Might it be that there are different SKUs?

Well, while it's in dts, but it was disabled in the kernel config:
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/blob/pipa-t-oss/arch/arm64/configs/vendor/pipa_user_defconfig#L413

Maybe they just forgot to remove it from dts (I still don't understand 
why it is displayed in i2cdetect though).

For PMIC you can check in
/sys/kernel/debug/soc/qcom_socinfo/pmic_model_array. For FG it's not
possible.
