[PATCH 12/22] kdrive/ephyr: Use shared NoopDDA to utilize code cache better

[Pauli]

From: Pauli Nieminen <ext-pauli.nieminen at nokia.com>

Calling function that is in code cache is order of magnitude faster. In
arm non-cached simple function takes about 1us while cached function
takes max 200ns.
