Subject: [PATCH] sm8550-common: Enable compilation of init_boot partition

Devices launching with Android 13 or higher and shipping with
Android 13 must have an init_boot static partition. The generic
ramdisk is no longer be contained in the boot.img file that goes
in the boot partition. This generic ramdisk will be placed in a
new init_boot.img to be installed in a new init_boot partition.
