DIAG traffic can go over USB, UART and SD card. Input received from SD
card needs to be validated before sending to modem. Whereas, traffic
from UART does not need such check.

Add support for relaying the MDM 9k diag traffic over HSIC
to the USB DIAG MDM channel and vice versa. Also modify usb
diag_bridge to use signed parameters for buffer sizes. This
is especially needed for the final parameter of the read
and write callbacks, wherein a negative errno value may be
passed to convey an error.

DIAG provides packet request/response service. A PC tool
can send a request and receive response from an app on
phone. In case, app is not running, the phone should return
an error response, which is almost same length as request.
A buffer overrun can happen, if the request is too huge. Thus,
adding a check to prevent buffer overrun.

DIAG char driver maintains registrations for remote processors in a table.
When the remote processor goes down, the registrations should be cleaned
up. This change adds the clean up process in event of a restart. Also when
the peripheral goes down for subsystem restart, the SMD channel between
apps processor and peripheral has to be set to NULL, to prevent further SMD
operations. When the peripheral comes back up, this SMD channel can be
re-initialized.

DIAG uses SMD control channels to transfer packet registration
information from slave processors. While USB is disconnected, under
some scenarios, the SMD data might be left unread. Hence, when USB
gets connected, a special effort has to be made to read any unread
data on SMD control channel. Also each time a registration information
is stored in diag table, the SMD channel needs to be polled once more.
