Phonet: kill the ST-Ericsson pipe controller Kconfig

Browse source 
This is now a run-time choice so that a single kernel can support both
old and new generation ISI modems. Support for manually enabling the
pipe flow is removed as it did not work properly, does not fit well
with the socket API, and I am not aware of any use at the moment.

socket descriptors that are already connected or being connected.
Phonet Pipe-controller Implementation
-------------------------------------
Phonet Pipe-controller is enabled by selecting the CONFIG_PHONET_PIPECTRLR
Kconfig option.
The implementation adds socket options at SOL_PNPIPE level:
PNPIPE_ENABLE accepts one integer value (int). If set to zero, the pipe
is disabled. If the value is non-zero, the pipe is enabled. If the pipe
is not (yet) connected, ENOTCONN is error is returned.

The Pipe Controller implementation in Phonet stack to support Pipe

platform.
This option is incompatible with older Nokia modems.
Say N here unless you really know what you are doing.
