Fix Clock Rescaling Bug (Introduced in #135)

Browse Source 
There was a mistake in the code-style refactor where the signature in the instruction encoding of `MRS` was set to `0xD54` instead of `0xD53` which would cause a SIGILL (Illegal Instruction) for devices which had their HW timer frequency equivalent to the Switch (19.2MHz) as a modified `MRS` would be deployed there. This issue should not affect devices which perform clock rescaling as the `MRS` instruction there is encoded by the assembler.
