Add support for vibrator module inside PMI632, PM7250B, PM7325B.
It is very similar to vibrator inside PM8xxx but just the drive
amplitude is controlled through 2 bytes registers.

I see that you are just expanding what was done for SSBI PMICs and
later expanded to support pm8916. However it might be better to drop
the hardcoded .drv_addr (and drv_addr2) and read address from DT
instead.

Right, this is the simplest change without updating the code logic too 
much. If we decided to read .drv_addr and .drv_add2 from DT, we will 
have to read .enable_addr along with all other mask/shift for each 
register address from DT as well because they are not consistent from 
target to target. I don't know how would you suggest to add the DT 
properties for all of them, but if we end up to add a property for each 
of them, it won't be cleaner than hard-coding them.
