gnu: ath9k-htc-firmware: Update binutils patch for binutils 2.27.

* gnu/packages/patches/ath9k-htc-firmware-binutils.patch: Remove
unnecessary and conflicting hunk. Add hunk required for binutils 2.27.

gnu/packages/patches/ath9k-htc-firmware-binutils.patch

-This Binutils patch is from the ath9k-htc-firmware repository (version 1.3.2).
-Not applying it (apparently) leads to miscompiled firmware, and loading it
-fails with a "Target is unresponsive" message from the 'ath9k_htc' module.
+These Binutils patches are from the ath9k-htc-firmware repository
+(commit f6af791348b68ceadab375e4ed0f7bcda86cb3c0).
+
+Not applying the first patch (apparently) leads to miscompiled firmware,
+and loading it fails with a "Target is unresponsive" message from the
+'ath9k_htc' module.
+
+The final hunk, applied to 'gas/config/tc-xtensa.c', is copied from the
+upstream file 'local/patches/binutils-2.27_fixup.patch'.
