regulator: qcom_smd: Fix up PM8950 regulator configuration

[ Upstream commit 5334875c2524625808cfa3f7cda8f892dcd6e60b ]

Following changes have been made:

- S5, L4, L18, L20 and L21 were removed (S5 is managed by
SPMI, whereas the rest seems not to exist [or at least it's blocked
by Sony Loire /MSM8956/ RPM firmware])

- Supply maps have were adjusted to reflect regulator changes.
