[edk2-devel] [PATCH v8 2/5] MdePkg: Rename Cache Management Function To Clarify Fence Based Op

[Dhaval Sharma]

There are different ways to manage cache on RISC-V Processors.
One way is to use fence instruction. Another way is to use CPU
specific cache management operation instructions ratified as
per RISC-V ISA specifications to be introduced in future
patches. Current method is fence instruction based, rename the
function accordingly to add that clarity.

Notes:
    V8:
    - Update function name to udpate *asm* in the end
    V7:
    - Add RB tag
    V6:
    - As part of restructuring, adding cache instruction differentiation
      in function naming
