SerDesPrtclMap is a UINT64 but the BIT() macro produces a UINT32, which
was causing SerDesPrtclMap to be filled with incorrect values when using
Serdes protocols numbered greater than 32.
This fixes a hang at boot time when I tried to use UEFI firmware with SERDES=4_5_2 on my Honeycomb.
The equivalent code in upstream edk2-platforms looks somewhat different but still seems to suffer the same int overflow undefined behaviour. But I'm sending this here first since it's of relevance to Honeycomb users.
