u-boot: Move UBOOT_INITIAL_ENV back to u-boot.inc

Commit cc6c3e31526d ("u-boot: Move definitions to common locations") moved
UBOOT_INITIAL_ENV to uboot-config.bbclass, but it should be kept at u-boot.inc
because it encodes ${PN} in it, which should be set by the U-Boot recipe.

Currently, whatever inherits uboot-config bbclass will fill-in its own PN,
which would change the content of UBOOT_INITIAL_ENV per-package.
