 Remove support for boot signal page.

 Remove support for bootparams and cmdline pages.

The need for bootparams and cmdline came from having a Linux secure kernel in
VTL1. With rust based Litebox as secure kernel, we no longer need these pages.
Instead pass the require boot info as arguments when primary cpu enters VTL1 the
first time to boot.

This need corresponding VTL0 Linux changes. Do not merge till that is ready. This was done as part of clean up for submitting the initial set of VTL0 patches upstream
