ARM: OMAP2+: Remove bogus warnings for machines without twl PMIC
In general we want to see a quiet dmesg output with no errors or warnings
unless something is really wrong and needs attention. We currently see
these bogus warnings on boot:
twl: not initialized
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
twl6030_uv_to_vsel:OUT OF RANGE! non mapped vsel for 1375000 Vs max 1316660
...
Let's avoid these by checking if a device tree node for cpcap PMIC exists.
