arm64: dts: qcom: msm8998: Don't pull-up I2C pins by default in sleep
When the I2C controller is disabled, no communication is expected to
take place. Without traffic on the bus, the pull-up is unnecessary.
Both the vendor kernel for this platform and DTs of other SoCs in
upstream concur this logic. Change the default and clean up now-NOP
overrides.
Fixes: 0fee55fc0de7 ("arm64: dts: qcom: msm8998: Add I2C pinctrl and fix BLSP2_I2C naming")
