Subject: [PATCH 3/7] regulator: qcom_spmi: Add PM660/PM660L regulators

From: AngeloGioacchino Del Regno <kholk11@...il.com>

The PM660 PMIC is very often paired with the PM660L option on
SDM630/663/660 (and SDA variants) boards.

The PM660 has 11 "660" LDOs (2 NMOS, 9 PMOS) and 7 HT LDOs (4 NMOS,
3 PMOS) and a quirk: the L4 regulator is unaccessible or does not
exist on the PMIC.
The PM660L has 8 "660" LDOs (1 NMOS, 7 PMOS) and 2 HT NMOS LDOs.
