Recovery: Fix a major fault in the partitions

The source of this map had numerous conflicting and counterproductive
flags placed on partitions to be accessed.
* System was marked as rewrite with write disabled later on
* Data was marked as read-only with writing also disabled
* Optimizations were enabled that prove useless in recovery
* Allow recovery to elevate the shell to root permissions
* Force SELinux permissive to avoid possible security error
umbrella_core: Expose base frequency to userspace

* Allows configuration to fully replace yankeractive
* Allow interactive to “only overclock on load > 99”
* Extend hispeed_freq to screen on and screen off
