[PATCH v3 23/24] fwu_arm_psa: corstone1000: Set Boot0001 for on-disk FWU

[abdellatif.elkhlifi at arm.com]

From: Abdellatif El Khlifi <abdellatif.elkhlifi at arm.com>

Set Boot0001 to point to the ESP partition path

On-disk FWU requires setting the boot option to where the
EFI System Partition (ESP) is so U-Boot's capsule driver
can detect the ESP partition and start the FWU.

Corstone-1000 supports on-disk FWU on FVP.
The ESP partition is at mmc 1:1 and is accessible with boot option 1.

To avoid setting manually Boot0001 at factory level, Boot0001 is
set in the bootcmd. So, before starting the on-disk FWU, the bootcmd
will be executed and Boot0001 will be set automatically.
