so rename the mid-x86 directory to intel as originally directory name
reflected only Intel MID platform.

BUG_ON() is rather useless for debugging as it leads to panic().

This is a follow up on 53dea36c which fixes the other affected
pcm engines.

Description from 53dea36c:
 Don't rely on the codec's channels_min information to decide wheter or
 not allocate a substream's DMA buffer. Rather check if the substream
 itself was allocated previously.

Without this patch I was seeing null-pointer dereferenc in atmel-pcm.

The variable ret_val is used but not declared. This causes
the following compile error:

sound/soc/mid-x86/sst_platform.c: In function ‘sst_platform_open’:
sound/soc/mid-x86/sst_platform.c:274:2: error: ‘ret_val’ undeclared (first use in this function)

make[1]: *** [sound/soc/mid-x86/sst_platform.o] Error 1

Fix this.

lower level drivers typically register with upper layers.
So fix by exporting symbols from sst_platform driver for dsp driver to
register to sst platform driver

Now this driver doesnt depend on sst driver, so remove the dependency
and the header files

snd_pcm_hw_constraint_integer() could return -1, in this case, sst platform is
not opened successfully.  However the corresponding close callback isn't able
to be called later on to release these two allocated memories, thus resulting
in memory leak.

This patch moves the check for hardware contraints earlier, thus resolving this
issue.

Currently pcm_new() passes in 3 arguments :- card, pcm and DAI.

Refactor this to only pass in 1 argument (i.e. the rtd) since struct rtd contains
card, pcm and DAI along with other members too that are useful too.
