Niklas Cassel 9c6e09a434 ata: fix ata_id_has_devslp()
ACS-5 section
7.13.6.36 Word 78: Serial ATA features supported
states that:

If word 76 is not 0000h or FFFFh, word 78 reports the features supported
by the device. If this word is not supported, the word shall be cleared
to zero.

(This text also exists in really old ACS standards, e.g. ACS-3.)

Additionally, move the macro to the other ATA_ID_FEATURE_SUPP macros
(which already have this check), thus making it more likely that the
next ATA_ID_FEATURE_SUPP macro that is added will include this check.

Fixes: 65fe1f0f66 ("ahci: implement aggressive SATA device sleep support")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
