Melissa Jost 3a06300988 stdlib: Modified LupV Platform + Board to use LupioPIC + TMR
This added both the LupioPIC and LupioTMR to the LupVBoard.  While
both the PLIC and CLINT are left in the board for the bootloader
to recognize, they aren't used within the system.  In addition, the
LupV Platform was changed in order to use the LupioPIC to handle
interrupts instead of the PLIC.
