[On Kria KV260]
Tested-by: Luca Ceresoli <luca.ceresoli@bootlin.com>
Reviewed-by: Luca Ceresoli <luca.ceresoli@bootlin.com>

In order to test I did, after applying the whole series:
- make zynqmp_kria_kv260_defconfig
- set BR2_TARGET_UBOOT_ZYNQMP_PMUFW_SOURCE=y
- set (for Kria):
  BR2_TARGET_ZYNQMP_FIRMWARE_CUSTOM_CFLAGS="-DBOARD_SHUTDOWN_PIN=2 \
    -DBOARD_SHUTDOWN_PIN_STATE=0 -DENABLE_EM -DENABLE_MOD_OVERTEMP \
    -DENABLE_DYNAMIC_MIO_CONFIG -DENABLE_IOCTL -DCONNECT_PMU_GPO_2_VAL=0"

And flashed the resulting boot.bin and u-boot.itb. The board boots
normally. Thanks to Neal for providing me these details.

I suggest adding a new patch in the v4 patchset to update the KV260
defconfig, so the entire patch set can be tested.

Luca
