Subject: iwlwifi: Fix MODULE_FIRMWARE() ucode definitions for SLE15-SP3
Patch-mainline: Never, SLE15-SP3 only
References: bsc#1183860

It seems that kernel-firmware package on SLE15-SP3 never contains *-56
ucode but only *-55 version for 22000 chips, while the driver declares
with the non-existing *-56 ucode with MODULE_FIRMARE().  This leads to
the broken WiFi setup on the installer image that takes only the
firmware files that are declared by the kernel modules.

Correct the IWL_22000_UCODE_API_MAX value to 55, the value matching
with the current setup.
