bnx2x: Separated FW from the source.

>From now on FW will be downloaded from the binary file using request_firmware.

There will be different files for every supported chip. Currently 57710 (e1) and
57711 (e1h).

File names have the following format: bnx2x-<chip version>-<FW version>.fw.
ihex versions of current FW files are submitted in the next patch.

Each binary file has a header in the following format:

struct bnx2x_fw_file_section {
	__be32 len;
	__be32 offset;

struct bnx2x_fw_file_hdr {
	struct bnx2x_fw_file_section init_ops;
	struct bnx2x_fw_file_section init_ops_offsets;
	struct bnx2x_fw_file_section init_data;
	struct bnx2x_fw_file_section tsem_int_table_data;
	struct bnx2x_fw_file_section tsem_pram_data;
	struct bnx2x_fw_file_section usem_int_table_data;
	struct bnx2x_fw_file_section usem_pram_data;
	struct bnx2x_fw_file_section csem_int_table_data;
	struct bnx2x_fw_file_section csem_pram_data;
	struct bnx2x_fw_file_section xsem_int_table_data;
	struct bnx2x_fw_file_section xsem_pram_data;
	struct bnx2x_fw_file_section fw_version;

Each bnx2x_fw_file_section contains the length and the offset of the appropriate
section in the binary file. Values are stored in the big endian format.

Data types of arrays:

init_data            __be32
init_ops_offsets     __be16
XXsem_pram_data         u8
XXsem_int_table_data    u8
init_ops             struct raw_op {
                          u8   op;
			__be24 offset;
                        __be32 data;
fw_version              u8

>From now boundaries of a specific initialization stage are stored in
init_ops_offsets array instead of being defined by separate macroes. The index 
in init_ops_offsets is calculated by BLOCK_OPS_IDX macro:

#define BLOCK_OPS_IDX(block, stage, end) \
       (2*(((block)*STAGE_IDX_MAX) + (stage)) + (end))


In addition to sanity check of array boundaries bnx2x will check a FW version.
Additional checks might be added in the future.
