[RFC PATCH 2/5] scripts: imx: Support CST version >= 2.3.2

[Marcin Niestroj <m.niestroj@grinn-global.com>]

New versions of CST (starting from 2.3.2 according to Release Notes)
require specifying '-i --input' option, instead of writing
configuration to standard input. I see few possibilities here:
1) Simply add '-i /dev/fd/0' as a fix to current implementation
   (this patch actually does that).
2) Reimplement code to save CSF content to file, instead of malloc'ed
   buffer.
3) Above methods will only support CST tool >= 2.3.2. To keep
   compatibility with older CST versions, we would need to check
   'cst -h' output to see if '-i' option is supported or not (note,
   that version returned by CST 2.3.3 is 'BLN_CST_MAIN_02.03.00').
