arm-bsp/u-boot: add recipe for 2023.07.02

Multiple machines in meta-arm-bsp have need of the 2023.07.02 version of
u-boot.  Temporarily add it here to give those machines enough time to
update to the latest version.

NOTE: MTD changes in u-boot require changes to the qemuarm config.
Specifically, not disabling it.
