ARM: mvebu: prepare pm-board.c for the introduction of Armada 38x support
The pm-board.c code contains the board-specific logic to enter suspend to RAM. Until now, the code supported only the Armada XP GP board, so all functions and symbols were named with armada_xp_gp. However, it turns out that the Armada 388 GP also uses the same 3 GPIOs protocol to talk to the PIC microcontroller that controls the power supply. Since we are going to re-use the same code with no change for Armada 38x, this commit renames the functions and symbols to use just "armada" instead of "armada_xp_gp". Better names can be found if one day other boards having a different protocol/mechanism are supported in the kernel.
