[PATCH] regulator: Fix desc_id for tps65023/6507x/65910

[Axel Lin]

The desc_id variable should not be a static variable.

The rest of the code assumes the desc_id must less than TPSxxxxx_NUM_REGULATOR.
If we set desc_id to be a static variable, checking the return value of
rdev_get_id() may return error.
