PPC boards are the only users of the current FPGA code which is littered
with manual relocation fixups.  Now that proper relocation is supported
for PPC boards, remove FPGA manual relocation.

Adds Support for Altera's Stratix II.

Within your board specific init file you will have to call

1. fpga_init (/* relocated code offset. usually => */ gd->reloc_off);
2. fpga_add (fpga_altera, (Altera_desc*)&altera_desc);

Altera_desc* contines (for example):
	{
	 Altera_StratixII,	/* part type */
	 passive_serial,	/* interface type */
	 1,			/* bytes of data part can accept */
	 (void *)(&funcs),	/* interface function table */
	 0L,			/* base interface address */
	 0			/* implementation specific cookie */
	 }

funcs is the interface. It is of type altera_board_specific_func.
It looks like this:
altera_board_specific_func func = {
	pre_fn,
	config_fn,
	status_fn,
	done_fn,
	clk_fn,
	data_fn,
	abort_fn,
	post_fn,
};

you will have to implement these functions, which is usually bit
banging some gpio.
