1. Modernize the boot parameters uboot passes to the kernel
2. Correct the volume keys. Upstream DTS actually sends F7 and F8 for these
keys, which is the behavior from stock. Using hwdb to correct the keys
allows us to drop the relevant DTS patch from linux-postmarketos-omap.
Additionally add the hwdb database into initramfs to ensure the keys
also work during system initialization
3. Disable OMAP 3430 OFF mode early in the initramfs. This is currently
broken and causes system instability. We previously used a DTS patch to
do this, but using an initramfs hook allows us to reduce the amount of
kernel patches we maintain
