arm64: dts: allwinner: a64-amarula-relic: Add OV5640 camera node 

Amarula A64-Relic board by default bound with OV5640 camera,
so add support for it with below pin information.

- PE13, PE12 via i2c-gpio bitbanging
- CLK_CSI_MCLK as external clock
- PE1 as external clock pin muxing
- ALDO1 as AVDD supply
- DLDO3 as DOVDD supply
- ELDO3 as DVDD supply
- PE14 gpio for reset pin
- PE15 gpio for powerdown pin
