Obsolete support for the 8051 family. Trying to maintain compatibility with this family is too much effort and there has never really been a successful NuttX impplementation on these parts

- * Name: up_initialize
- *
- * Description:
- *   up_initialize will be called once during OS
- *   initialization after the basic OS services have been
- *   initialized.  The architecture specific details of
- *   initializing the OS will be handled here.  Such things as
- *   setting up interrupt service routines, starting the
- *   clock, and registering device drivers are some of the
- *   things that are different for each processor and hardware
- *   platform.
- *
- *   up_initialize is called after the OS initialized but
- *   before the init process has been started and before the
- *   libraries have been initialized.  OS services and driver
- *   services are available.
- *
