Renesas R-Car can out TDM by
1) 6ch x 1 DAI as TDM Extend Mode
2) 2ch x 4 x 1 DAI as TDM split Mode
3) 2ch x 3 DAI or
2ch x 4 DAI as TDM Multichannel Mode
This patch adds 1) TDM Extend Mode. Because of HW design,
this 6ch data will be outputed via 8ch data width.

Current SSI is assuming that the sound is always stereo. But, SSI needs
to calculate its frequency when master mode. Then This frequency depends
on each SSI's slots, and TDM mode (= TDM Extend Mode, TDM split Mode,
TDM Multichannel Mode).
This patch enables to use non-stereo sound.

It will have TDM settings on SSIWSR. Actually, we would like to set
it on rsnd_ssi_config_init(), but we can't. Because SSI might be used
as clock master (It doesn't need to call rsnd_ssi_config_init() when
clock master mode).
This patch adds new ssi->wsr and set it on rsnd_ssi_start().

Assume a filesystem with 4KB blocks. When a file has size 1000 bytes and
we issue direct IO read at offset 1024, blockdev_direct_IO() reads the
tail of the last block and the logic for handling short DIO reads in
dio_complete() results in a return value -24 (1000 - 1024) which
obviously confuses userspace.
Fix the problem by bailing out early once we sample i_size and can
reliably check that direct IO read starts beyond i_size.
