Subject: [PATCH v3] arm64: dts: freescale: debix-som-a-bmb-08: Add CSI Power Regulators

Provide the 1.8 and 3.3 volt regulators that are utilised on the Debix
SOM BMB-08 base board.

Facilitate this by also supplying the pin control used to enable the
regulators on the second MIPI CSI port.

v3:
- Fix line ordering within reg_csi1_1v8

v2:
- Remove _SW post fixes from regulators.
