Verify if the provided signature is valid for the specified data. The public key
is provided by the system software.

Note:
	The ECDSA algorithm is used to verify a signature.

Parameters:
	pData	Pointer to data the signature has to be verified for. Data length: KIRK_ECDSA_SRC_DATA_LEN.
	pSig	Pointer to the signature to verify. Signature length: KIRK_ECDSA_SIG_LEN.

Returns:
