Simplify code by using local array instead of dynamic allocation. Moreover store the FlashId in an UINT8 array PCD instead of the concatenated UINT32 format - this way less overhead in the driver is needed for comparing the buffers. The new handling allowed for cleaning Fupdate and Sf shell commands FlashProbe routines.
