simplelink_lpf3: ti: devices: cc23x0r5: Fix not sufficient flash status

bogdanovs · jpanisbl · commit cff5359e8caf · 2024-07-29T16:28:50.000+02:00
Fix FlashCheckFsmForReady which always returns FSM_BUSY if nothing was
written to flash before check. Default STATCMD reg value indicates
that CMDDONE - false. If CMDINPROGRES is ok, it is safe to continue.
