1. some arm instructions are not compatible with arch tlsr:
{standard input}: Assembler messages:
{standard input}:53: Error: bad instruction `svc #0'
2. remove unsupport compile option
cc1: error: unrecognized command line option "-mlittle-endian"

and remove CONFIG_LIBC_LONG_LONG option to simplify the usage.
note: the size will increase 668

RF and system timer interrupt are used for ble.
tlsr82_flash.c:
1. BLE will loss packets during flash operation beacause the interrupt
is disabled and the operation take too long (especially erasing,
about 100ms), so allow RF and system timer interrupt during flash
operation;
2. Add sched_lock()/sched_unlock() to avoid the task switch in ble and
system timer interrupt;
flash_boot_ble.ld:
3. Because of 1, the code executes in RF and system timer interrupt
must be in ram to avoid bus error. The sem_post() will be called and
const variable g_tasklisttable will be accessed in RF and system
timer interrupt handler;
4. To improve the performance, copy some frequently called function to
ram as well, such as: sem_take(), sched_lock(), sched_unlock(),
some lib functions, some zephyr ble functions and some tinycrypt
functions;
5. The RF and system timer interrupt handler will call some libgcc
functions, so copy all the libgcc functions to ram exclude _divdi3.o,
_udivdi3.o and _umoddi3.o;
tlsr82_serial.c
6. Make up_putc() be thread safe, add enter/leave_critical_section() in
function uart_send_byte();
tc32_doirq.c
7. Increase the RF and system timer interrupt response priority;
