mfd: AB3100 OTP readout
This adds the ability to read out OTP (One-Time Programmable) registers in the AB3100 MFD ASIC. It's a simple sysfs file you can cat to prompt. The OTP registers of the AB3100 are used to store various device-unique information such as customer ID, product flags and the 3GPP standard IMEI (International Mobile Equipment Indentity) number.
