[PATCH 19/20] crypto: nx: Demote header comment and add description for 'nbytes'

[Lee Jones]

Fixes the following W=1 kernel build warning(s):

 drivers/crypto/nx/nx.c:31: warning: Incorrect use of kernel-doc format:  * nx_hcall_sync - make an H_COP_OP hcall for the passed in op structure
 drivers/crypto/nx/nx.c:43: warning: Function parameter or member 'nx_ctx' not described in 'nx_hcall_sync'
 drivers/crypto/nx/nx.c:43: warning: Function parameter or member 'op' not described in 'nx_hcall_sync'
 drivers/crypto/nx/nx.c:43: warning: Function parameter or member 'may_sleep' not described in 'nx_hcall_sync'
 drivers/crypto/nx/nx.c:43: warning: expecting prototype for Nest Accelerators driver(). Prototype was for nx_hcall_sync() instead
 drivers/crypto/nx/nx.c:209: warning: Function parameter or member 'nbytes' not described in 'trim_sg_list'
