pinctrl: qcom: kaanapali: add the I2C strong pull-up bit
The Kaanapali TLMM has the I2C pull-up control in bit 13 of the pin
config register, like SM8550, SM8650 and X1E80100, but the driver does
not describe it, so "bias-pull-up = <2200>" cannot select the strong
pull-up.
The downstream kernel sets it on the camera CCI pins (config 0x2007).
On a Lenovo TB323FU tablet, with only the weak pull-up every CCI
transfer on the two sensor buses times out; with bit 13 set the sensors
answer and their chip IDs read correctly.
