reset command not enabled for PolarFire Icicle Kit

[Heinrich Schuchardt]

[ Impact ]

The HSS v2022.10 firmware supports resetting the Polar Icicle Kit development board via SBI. We should enable the reset command. An upstream patch for the defconfig is available:

[PATCH 1/1] riscv: enable reset via SBI on PolarFire Icicle Kit
https://lists.denx.de/pipermail/u-boot/2022-November/499280.html

This patch only affects the u-boot-microchip package.

We plan to provide a Jammy image with the Ubuntu 22.04.1 release. This change already is in Jammy proposed. If a user upgrades from Jammy to Kinetic, this should not downgrade the experience.

[ Test Plan ]

Install U-Boot on the PolarFire Icicle Kit.
Check that the reset command in U-Boot can be used to reset the board.
Check that the board boots properly after reset.

[ Where problems could occur ]

Resetting the PolarFire Icicle Kit board from U-Boot might fail.

Resetting from Linux directly calls into OpenSBI and therefore is not affected by the change.
