bastion: add Kernel, Processor, AcpiTables, DeviceTree classesHEADmaster

Kernel: main singleton object, that provide access to core kernel
entities
Processor: empty class, that will be used later for per-CPU entities
AcpiTables: class for acpi access (can be obtained through the kernel
object)
DeviceTree: class for dt access (can be obtained through the kernel
object)
