In release/release.sh:

• Rename chroot_arm_armv6_build_release() to chroot_arm_build_release() and make it hardware agnostic (such as armv6 -vs- armv7 -vs- arm64).

• Evaluate EMBEDDED_TARGET differently so release/tools/arm.subr can be used for arm/armv6 and arm64/aarch64.

• Update comments and copyright.

In release/tools/arm.subr:

• In arm_create_disk(), change the default alignment from 63 to 512k, fixing a boot issue on arm64 and EFI. [1]

• Update comments and copyright.
