References: git-fixes

Patch-mainline: v4.19-rc5

Git-commit: edf2ef7242805e53ec2e0841db26e06d8bc7da70

Synopsys DWC Ethernet MAC can be configured to have 1..32, 64, or

128 unicast filter entries. (Table 7-8 MAC Address Registers from

databook) Fix dwmac1000_validate_ucast_entries() to accept values

between 1 and 32 in addition.
