[Patch] UefiCpuPkg RegisterCpuFeaturesLib: Fix buffer pointer error usage.

[Eric Dong]

Current code allocate buffer for the pointer which later get value
from PCD database. but current code error use "=" for this case.
Use CopyMem instead to fix it.

[Ni, Ruiyu]

How about to use AllocateCopyPool()?

[Patch] UefiCpuPkg RegisterCpuFeaturesLib: Fix buffer pointer error usage.

[Eric Dong]

Current code allocate buffer for the pointer which later get value
from PCD database. but current code error use "=" for this case.
Use AllocateCopyPool instead to fix it.

V2 enhanced to directly use AllocateCopyPool to get the PCD value.
V3 enhanced to avoid using local temp variable.

Re: [Patch] UefiCpuPkg RegisterCpuFeaturesLib: Fix buffer pointer error usage.

[Kinney, Michael D]

Hi Eric,

I think we should keep the Getxxx() functions to make
the code easier to read and we have matched Get/Set
functions to access these PCDs.
