ENGR00161487: Fix SD/USB/FEC performance issue.er3-preview
When WAIT mode is not enabled, execute cpu_do_idle() code.
Currently WAIT mode requires the code to be run from IRAM with caches disabled.
No L2 cache access should be done for a specified period after the system exits
WAIT mode. This delay and running code from IRAM adversely affects the
SDHC performance.
Hardware team is looking into the extended delay that is required.
Till its root caused, default should be to execute cpu_do_idle() and
disable entry into WAIT mode.
