target: clean up kernel-doc and add driver-api document

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

This patch series fixes kernel-doc warnings in drivers/target/ and
its header files, then adds a Documentation driver-api chapter for
target driver interfaces.

[PATCH v3 1/4] target: target_core_transport.c: fix kernel-doc warnings

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Correct a function parameter's name to eliminate kernel-doc warnings
in drivers/target/target_core_transport.c.

Fixes these kernel-doc warnings: (tested by adding these files to a new
target.rst documentation file)

../drivers/target/target_core_transport.c:1671: warning: No description found for parameter 'fabric_tmr_ptr'
../drivers/target/target_core_transport.c:1671: warning: Excess function parameter 'fabric_context' description in 'target_submit_tmr'

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

For exported functions that already have near-kernel-doc notation,
fix them to begin with "/**" and make a few corrections so that they
don't have any kernel-doc warnings.
