regulator: palmas: remove redundant initialization of pointer pdata

Pointer pdata is being initialized with a value that is never read. It is
being re-assigned later on with the return from a devm_kzalloc call.
Remove the redundant initialization, cleans up clang scan build warning:

drivers/regulator/palmas-regulator.c:1597:36: warning: Value stored
to 'pdata' during its initialization is never read [deadcode.DeadStores]
