Closes #15 Remove kernel patch changing cpu_up to EXPORT_SYMBOL
Update README in patches/linux-4.19-cs for change
Remove symbols from patched kernel in src/drv/ExtraSymbols.symvers
Add parameter in GNUmakefile to build will reference Module.symvers from kernel

Disable CONFIG_DRM_AST flag so kernel uses 'nomodeset' on AST VGA chips
which prevents interrupts causing long IOP cycles on newer front-ends
(and removes need for nomodeset as kernel boot parameter)
Update README in patches/linux-4.19-cs for these changes
