Create tas2781 driver.

Signed-off-by: Shenghao Ding <13916275206@139.com>

---
Changes in v9:
 - rewording some commets
 - Add comments on fimware parsing error handling -- all the memory resources
    will be released in the end of tasdevice_rca_ready (fw_parse_data,
    fw_parse_program_data & fw_parse_configuration_data).
 - Add comments on fw_parse_calibration_data -- DSP can still work with default
    calibrated data, memory resource related to calibrated data will be released
    in the tasdevice_codec_remove.

I have a question regarding those
if (offset + x > fmw->size) {
	do error
}
offset += x;

Can you instead of doing check before every assignment, just check once 
if you have enough data to parse, before parsing whole piece of data 
instead?

For above function it would be something like:

static int fw_parse_block_data_kernel(struct tasdevice_fw *tas_fmw,
	struct tasdev_blk *block, const struct firmware *fmw, int offset)
{
	const unsigned char *data = fmw->data;

	if (offset + 16 + block->blk_size > fmw->size) {
		dev_err(tas_fmw->dev, "%s: File Size error\n", __func__);
		offset = -EINVAL;
		goto out;
	}
	block->type = SMS_HTONL(data[offset], data[offset + 1],
		data[offset + 2], data[offset + 3]);
	block->is_pchksum_present = data[offset + 4];
	block->pchksum = data[offset + 5];
	block->is_ychksum_present = data[offset + 6];
	block->ychksum = data[offset + 7];
	block->blk_size = SMS_HTONL(data[offset + 8], data[offset + 9],
		data[offset + 10], data[offset + 11]);
	block->nr_subblocks = SMS_HTONL(data[offset + 12], data[offset + 13],
		data[offset + 14], data[offset + 15]);
	offset += 16;

	block->data = kmemdup(&data[offset], block->blk_size, GFP_KERNEL);
	if (!block->data) {
		offset = -ENOMEM;
		goto out;
	}
	offset += block->blk_size;

out:
	return offset;
}

Additionally if you defined 'struct tasdev_blk' to reflect data which 
you copy here it can probably be simplified further to simple memcpy, 
instead of doing field by field assignments, which would reduce amount 
of code significantly and make it easier to read.


Above applies to all similar parsing in the patch.

Kernel has htons and htonl (in 
source/include/linux/byteorder/generic.h), but I assume that this means 
that your FW may use different endianness than host cpu (big endian?), 
so I would suggest using be16_to_cpu and be32_to_cpu macros instead, as 
this should be more understandable in this case.
