soc: qcom: socinfo: rename PM2250 to PM4125

It seems, the only actual mentions of PM2250 can be found are related to
the Qualcomm RB1 platform. However even RB1 schematics use PM4125 as a
PMIC name. Rename PM2250 to PM4125 to follow the documentation.

There are some IDs that are written in uppercase. For consistency
convert them to lowercase.

mfd: qcom-spmi-pmic: read fab id on supported PMICs

The PMI8998 and PM660 expose the fab_id, this is needed by drivers like
the RRADC to calibrate ADC values.

mfd: qcom-spmi-pmic: expose the PMIC revid information to clients

Some PMIC functions such as the RRADC need to be aware of the PMIC
chip revision information to implement errata or otherwise adjust
behaviour, export the PMIC information to enable this.

This is specifically required to enable the RRADC to adjust
coefficients based on which chip fab the PMIC was produced in,
this can vary per unique device and therefore has to be read at
runtime.
