arm64: zynqmp: Add System Controller for a2197-g/p
Similar SCs but different wiring.
- dc_i2c is connected to X-PRC cards that's why label is required to have
an option to hook up some devices.
- Exactly identify i2c devices on x-prc boards.
In case of missing i2c connection devices won't be accessible.
- USB 0 should be device mode with super speed.
- USB 1 should be host mode.
- Fix i2c mux reset pin entry - commented, not verified.
- Fix i2c1 eeprom compatible string - it is an ST 128Kbit device.
Need to use atmel fallback.
- Fix si570 I2C slave address and add corresponding part numbers.
- Enable AMS for system monitoring.
- phy reset property should be commented because it will throw a
warning dump when called from context that can sleep.
No support for phys property (zynqmp phy driver) with SGMII.
Add is-internal-pcspma property required by uboot.
