Mauro Carvalho Chehab 54a19b4d3f docs: ABI: cleanup several ABI documents
There are some ABI documents that, while they don't generate
any warnings, they have issues when parsed by get_abi.pl script
on its output result.

Address them, in order to provide a clean output.

Description:
These debugfs interfaces are built by the nx-crypto driver, built in
arch/powerpc/crypto/nx.
Error Detection
===============
errors:
A u32 providing a total count of errors since the driver was loaded. The
only errors counted here are those returned from the hcall, H_COP_OP.
last_error:
The most recent non-zero return code from the H_COP_OP hcall. -EBUSY is not
recorded here (the hcall will retry until -EBUSY goes away).
last_error_pid:
The process ID of the process who received the most recent error from the
hcall.
Device Use
==========
aes_bytes:
The total number of bytes encrypted using AES in any of the driver's
supported modes.
aes_ops:
The total number of AES operations submitted to the hardware.
sha256_bytes:
The total number of bytes hashed by the hardware using SHA-256.
sha256_ops:
The total number of SHA-256 operations submitted to the hardware.
sha512_bytes:
The total number of bytes hashed by the hardware using SHA-512.
sha512_ops:
The total number of SHA-512 operations submitted to the hardware.
