arm64: dts: actions: Add uSD and eMMC support for Bubblegum96
Add uSD and eMMC support for Bubblegum96 board based on Actions Semi Owl SoC. SD0 is connected to uSD slot and SD2 is connected to eMMC. Since there is no PMIC support added yet, fixed regulator has been used as a regulator node. Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>
