Utilize msm-firmware-loader for minimize device specific
firmware package.
Add necessary modules to initramfs for fix fde.
Use soc-qcom-msm8953-modem and soc-qcom-msm8953-initramfs as a dependency.
Add pmb:cross-native/!tracedeps to applicable firmware packages and
secure both with a test.
This sets the pmb:cross-native and !tracedeps options on all firmware-*
packages that are compatible with the native compilation method. A unit
test ensures the presence of both options while maintaining a list of
exempted packages.
