Subject: [PATCH] Bluetooth: Apply initial command workaround for more Intel chips

It seems that a few more Intel chips require the workaround for the
broken initial command.  At least, per openSUSE Bugzilla reports,
8087:0a2a and 8087:0026 need BTUSB_INTEL_BROKEN_INITIAL_NCMD flag.

Fixes: 83f2dafe2a62 ("Bluetooth: btintel: Refactoring setup routine for legacy ROM sku")
