PD#SWPL-1909
Problem:
On 32bit kernel, codec cma is located in normal zone by
"alloc-ranges" parameter with large size. This takse up
memory space for kernel and drivers. Sometimes we can see
memory allocation fail log but there are still enought
free pages. But most of these pages are CMA pages.
Solution:
Move codec cma location to high memzone. On 32bit, low
768MB memory is normal zone.
This change also correct first 1MB memory lost problem
for chips later than TXLX

Problem:
audio crash when ATV switch channel long time burning test
Solution:
there is a risk to fetch the timer lock. when input stop, stop_timer
will call del_timer, at the same time the function
"aml_i2s_hrtimer_callback" is waiting for the timer lock,after
stop_timer release the lock,"aml_i2s_hrtimer_callback" get the
lock and call mod_timer again, which will set the timer to pending
status. It will cause the next "start input" stage,add_timer will
trigger BUG_ON.Now we put the lock before the active status
checking then we will not touch the timer.
Verify:
Need burning test
