[dv/otp_ctrl] regwen sequence This PR adds a regwen sequence in OTP_CTRL. The timing to check direct_access_regwen is very sensitive because it is written by HW and write to 0 only when DAI operation is in-progress. This PR follows keymgr's cfgen sequence example and read direct_access_regwen register during DAI busy, and write one of the enabled registers when access is locked.
