[PATCH] ARM: dts: owl-s500-roseapplepi: Add ATC2603C PMIC

[Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>]

From: Cristian Ciocaltea <cristian.ciocaltea@gmail.com>

Add device tree node for ATC2603C PMIC and remove the 'fixed-3.1V'
dummy regulator used for the uSD supply.

Additionally, add 'SYSPWR' fixed regulator and provide cpu0 supply.

Just a single patch for v5.13, so sending it directly. The corresponding
driver and binding patches are merged into mfd tree.
