[PATCH RESEND] regulator: lp87565: Fix probe failure for "ti,lp87565"

[PATCH RESEND] regulator: lp87565: Fix probe failure for "ti,lp87565"

[Axel Lin]

The "ti,lp87565" compatible string is still in of_lp87565_match_table,
but current code will return -EINVAL because lp87565->dev_type is unknown.
This was working in earlier kernel versions, so fix it.
