qat: Make it compatible with kernel 5.6

Add qat17_4.7.0-00006-make-it-compitable-with-kernel-5.6.patch
when compiling qat with kernel 5.6.

In the patch, replace struct timespec with y2038 safe struct timespec64.
And add definition of CRYPTO_TFM_RES_BAD_KEY_LEN back for qat driver.

+Subject: [PATCH] qat17: make it compatible with kernel 5.6
+
+1) In kernel commit c766d1472c70 ("y2038: hide timeval/timespec/itimerval
+/itimerspec types"), timespec was hiden, so change timespec to timespec64.
+
+2) CRYPTO_TFM_RES_BAD_KEY_LEN was removed in kernel commit 674f368a952c
+("crypto: remove CRYPTO_TFM_RES_BAD_KEY_LEN"). Add it back, since qat driver
+needs it.
+
+Upstream-Status: Inappropriate [Code released in tarball form only]
